 = Gerrit Code Review - Searching Changes

 == Default Searches

 Most basic searches can be viewed by clicking on a link along the top
 menu bar.  The link will prefill the search box with a common search
 query, execute it, and present the results.  If exactly one change
 matches the search, the change will be presented instead of a list.


 [options="header"]
 |=================================================
 |Description          | Default Query
 |All > Open           | status:open '(or is:open)'
 |All > Merged         | status:merged
 |All > Abandoned      | status:abandoned
 |My > Drafts          | is:draft
 |My > Watched Changes | status:open is:watched
 |My > Starred Changes | is:starred
 |My > Draft Comments  | has:draft
 |Open changes in Foo  | status:open project:Foo
 |=================================================


 == Basic Change Search

 Similar to many popular search engines on the web, just enter some
 text and let Gerrit figure out the meaning:

 [options="header"]
 |=============================================================
 |Description                      | Examples
 |Legacy numerical id              | 15183
 |Full or abbreviated Change-Id    | Ic0ff33
 |Full or abbreviated commit SHA-1 | d81b32ef
 |Email address                    | user@example.com
 |Approval requirement             | Code-Review>=+2, Verified=1
 |=============================================================


 == Search Operators

 Operators act as restrictions on the search.  As more operators
 are added to the same query string, they further restrict the
 returned results. Search can also be performed by typing only a
 text with no operator. It will try to match a project name by
 substring.

 E.g. Searching for just "gerrit is:starred" will try to match a
 project name by "gerrit" as substring.

 [[age]]
 age:'AGE'::
 +
 Amount of time that has expired since the change was last updated
 with a review comment or new patch set.  The age must be specified
 to include a unit suffix, for example `age:2d`:
 +
 * s, sec, second, seconds
 * m, min, minute, minutes
 * h, hr, hour, hours
 * d, day, days
 * w, week, weeks (`1 week` is treated as `7 days`)
 * mon, month, months (`1 month` is treated as `30 days`)
 * y, year, years (`1 year` is treated as `365 days`)

 [[before_until]]
 before:'TIME'/until:'TIME'::
 +
 Changes modified before the given 'TIME', inclusive. Must be in the
 format `2006-01-02[ 15:04:05[.890][ -0700]]`; omitting the time defaults
 to 00:00:00 and omitting the timezone defaults to UTC.

 [[after_since]]
 after:'TIME'/since:'TIME'::
 +
 Changes modified after the given 'TIME', inclusive. Must be in the
 format `2006-01-02[ 15:04:05[.890][ -0700]]`; omitting the time defaults
 to 00:00:00 and omitting the timezone defaults to UTC.

 [[change]]
 change:'ID'::
 +
 Either a legacy numerical 'ID' such as 15183, or a newer style
 Change-Id that was scraped out of the commit message.

 [[conflicts]]
 conflicts:'ID'::
 +
 Changes that conflict with change 'ID'. Change 'ID' can be specified
 as a legacy numerical 'ID' such as 15183, or a newer style Change-Id
 that was scraped out of the commit message.

 [[owner]]
 owner:'USER', o:'USER'::
 +
 Changes originally submitted by 'USER'. The special case of
 `owner:self` will find changes owned by the caller.

 [[ownerin]]
 ownerin:'GROUP'::
 +
 Changes originally submitted by a user in 'GROUP'.

 [[reviewer]]
 reviewer:'USER', r:'USER'::
 +
 Changes that have been, or need to be, reviewed by 'USER'. The
 special case of `reviewer:self` will find changes where the caller
 has been added as a reviewer.

 [[reviewerin]]
 reviewerin:'GROUP'::
 +
 Changes that have been, or need to be, reviewed by a user in 'GROUP'.

 [[commit]]
 commit:'SHA1'::
 +
 Changes where 'SHA1' is one of the patch sets of the change.

 [[project]]
 project:'PROJECT', p:'PROJECT'::
 +
 Changes occurring in 'PROJECT'. If 'PROJECT' starts with `^` it
 matches project names by regular expression.  The
 link:http://www.brics.dk/automaton/[dk.brics.automaton
 library] is used for evaluation of such patterns.

 [[parentproject]]
 parentproject:'PROJECT'::
 +
 Changes occurring in 'PROJECT' or in one of the child projects of
 'PROJECT'.

 [[branch]]
 branch:'BRANCH'::
 +
 Changes for 'BRANCH'.  The branch name is either the short name shown
 in the web interface or the full name of the destination branch with
 the traditional 'refs/heads/' prefix.
 +
 If 'BRANCH' starts with `^` it matches branch names by regular
 expression patterns.  The
 link:http://www.brics.dk/automaton/[dk.brics.automaton
 library] is used for evaluation of such patterns.

 [[topic]]
 topic:'TOPIC'::
 +
 Changes whose designated topic at upload was 'TOPIC'.  This is
 often combined with 'branch:' and 'project:' operators to select
 all related changes in a series.
 +
 If 'TOPIC' starts with `^` it matches topic names by regular
 expression patterns.  The
 link:http://www.brics.dk/automaton/[dk.brics.automaton
 library] is used for evaluation of such patterns.

 [[ref]]
 ref:'REF'::
 +
 Changes where the destination branch is exactly the given 'REF'
 name.  Since 'REF' is absolute from the top of the repository it
 must start with 'refs/'.
 +
 If 'REF' starts with `^` it matches reference names by regular
 expression patterns.  The
 link:http://www.brics.dk/automaton/[dk.brics.automaton
 library] is used for evaluation of such patterns.

 [[tr,bug]]
 tr:'ID', bug:'ID'::
 +
 Search for changes whose commit message contains 'ID' and matches
 one or more of the
 link:config-gerrit.html#trackingid[trackingid sections]
 in the server's configuration file.  This is typically used to
 search for changes that fix a bug or defect by the issue tracking
 system's issue identifier.

 [[label]]
 label:'VALUE'::
 +
 Matches changes where the approval score 'VALUE' has been set during
 a review.  See <<labels,labels>> below for more detail on the format
 of the argument.

 [[message]]
 message:'MESSAGE'::
 +
 Changes that match 'MESSAGE' arbitrary string in the commit message body.

 [[comment]]
 comment:'TEXT'::
 +
 Changes that match 'TEXT' string in any comment left by a reviewer.

 [[path]]
 path:'PATH'::
 +
 Matches any change touching file at 'PATH'. By default exact path
 matching is used, but regular expressions can be enabled by starting
 with `^`.  For example, to match all XML files use `file:^.*\.xml$`.
 The link:http://www.brics.dk/automaton/[dk.brics.automaton library]
 is used for the evaluation of such patterns.
 +
 The `^` required at the beginning of the regular expression not only
 denotes a regular expression, but it also has the usual meaning of
 anchoring the match to the start of the string.  To match all Java
 files, use `file:^.*\.java`.
 +
 The entire regular expression pattern, including the `^` character,
 should be double quoted when using more complex construction (like
 ones using a bracket expression). For example, to match all XML
 files named like 'name1.xml', 'name2.xml', and 'name3.xml' use
 `file:"^name[1-3].xml"`.

 [[file]]
 file:'NAME', f:'NAME'::
 +
 Matches any change touching a file containing the path component
 'NAME'.  For example a `file:src` will match changes that modify
 files named `gerrit-server/src/main/java/Foo.java`. Name matching
 is exact match, `file:Foo.java` finds any change touching a file
 named exactly `Foo.java` and does not match `AbstractFoo.java`.
 +
 Regular expression matching can be enabled by starting the string
 with `^`. In this mode `file:` is an alias of `path:` (see above).

 [[has]]
 has:draft::
 +
 True if there is a draft comment saved by the current user.

 has:star::
 +
 Same as 'is:starred', true if the change has been starred by the
 current user.

 [[is]]
 is:starred::
 +
 Same as 'has:star', true if the change has been starred by the
 current user.

 is:watched::
 +
 True if this change matches one of the current user's watch filters,
 and thus is likely to notify the user when it updates.

 is:reviewed::
 +
 True if there is at least one non-zero score on the change, in any
 approval category, by any user.

 is:owner::
 +
 True on any change where the current user is the change owner.
 Same as `owner:self`.

 is:reviewer::
 +
 True on any change where the current user is a reviewer.
 Same as `reviewer:self`.

 is:open::
 +
 True if the change is either open or submitted, merge pending.

 is:draft::
 +
 True if the change is a draft.

 is:closed::
 +
 True if the change is either merged or abandoned.

 is:submitted, is:merged, is:abandoned::
 +
 Same as <<status,status:'STATE'>>.

 [[mergeable]]
 is:mergeable::
 +
 True if the change has no merge conflicts and could be merged into its
 destination branch.

 [[status]]
 status:open::
 +
 True if the change state is either 'review in progress' or 'submitted,
 merge pending'.

 status:reviewed::
 +
 Same as 'is:reviewed', matches if there is at least one non-zero
 score on the change, in any approval category, by any user.

 status:submitted::
 +
 Change has been submitted, but is waiting for a dependency.

 status:closed::
 +
 True if the change is either 'merged' or 'abandoned'.

 status:merged::
 +
 Change has been merged into the branch.

 status:abandoned::
 +
 Change has been abandoned.


 == Argument Quoting

 Operator values that are not bare words (roughly A-Z, a-z, 0-9, @,
 hyphen, dot and underscore) must be quoted for the query parser.

 Quoting is accepted as either double quotes
 (e.g.  `message:"the value"`) or as matched
 curly braces (e.g. `message:{the value}`).


 == Boolean Operators

 Unless otherwise specified, operators are joined using the `AND`
 boolean operator, thereby restricting the search results.

 Parentheses can be used to force a particular precedence on complex
 operator expressions, otherwise OR has higher precedence than AND.

 === Negation
 Any operator can be negated by prefixing it with `-`, for example
 `-is:starred` is the exact opposite of `is:starred` and will
 therefore return changes that are *not* starred by the current user.

 The operator `NOT` (in all caps) is a synonym.

 === AND
 The boolean operator `AND` (in all caps) can be used to join two
 other operators together.  This results in a restriction of the
 results, returning only changes that match both operators.

 === OR
 The boolean operator `OR` (in all caps) can be used to find changes
 that match either operator.  This increases the number of results
 that are returned, as more changes are considered.


 [[labels]]
 == Labels
 Label operators can be used to match approval scores given during
 a code review.  The specific set of supported labels depends on
 the server configuration, however the `Code-Review` label is provided
 out of the box.

 A label name is any of the following:

 * The label name.  Example: `label:Code-Review`.

 * The label name followed by a ',' followed by a reviewer id or a
   group id.  To make it clear whether a user or group is being looked
   for, precede the value by a user or group argument identifier
   ('user=' or 'group=').  If an LDAP group is being referenced make
   sure to use 'ldap/<groupname>'.

 A label name must be followed by a score, or an operator and a score.
 The easiest way to explain this is by example.

 `label:Code-Review=2`::
 `label:Code-Review=+2`::
 `label:Code-Review+2`::
 +
 Matches changes where there is at least one +2 score for Code-Review.
 The + prefix is optional for positive score values.  If the + is used,
 the = operator is optional.

 `label:Code-Review=-2`::
 `label:Code-Review-2`::
 +
 Matches changes where there is at least one -2 score for Code-Review.
 Because the negative sign is required, the = operator is optional.

 `label:Code-Review=1`::
 +
 Matches changes where there is at least one +1 score for Code-Review.
 Scores of +2 are not matched, even though they are higher.

 `label:Code-Review>=1`::
 +
 Matches changes with either a +1, +2, or any higher score.

 `label:Code-Review=+2,aname`::
 +
 Matches changes with a +2 code review where the reviewer or group is aname.

 `label:Code-Review=2,user=jsmith`::
 +
 Matches changes with a +2 code review where the reviewer is jsmith.

 `label:Code-Review=+1,group=ldap/linux.workflow`::
 +
 Matches changes with a +1 code review where the reviewer is in the
 ldap/linux.workflow group.

 `label:Code-Review<=-1`::
 +
 Matches changes with either a -1, -2, or any lower score.

 `is:open label:Code-Review+2 label:Verified+1 NOT label:Verified-1 NOT label:Code-Review-2`::
 +
 Matches changes that are ready to be submitted.

 `is:open (label:Verified-1 OR label:Code-Review-2)`::
 +
 Changes that are blocked from submission due to a blocking score.


 == Magical Operators

 Most of these operators exist to support features of Gerrit Code
 Review, and are not meant to be accessed by the average end-user.
 However, they are recognized by the query parser, and may prove
 useful in limited contexts to administrators or power-users.

 visibleto:'USER-or-GROUP'::
 +
 Matches changes that are visible to 'USER' or to anyone who is a
 member of 'GROUP'.  Here group names may be specified as either
 an internal group name, or if LDAP is being used, an external LDAP
 group name.  The value may be wrapped in double quotes to include
 spaces or other special characters.  For example, to match an LDAP
 group: `visibleto:"CN=Developers, DC=example, DC=com"`.
 +
 This operator may be useful to test access control rules, however a
 change can only be matched if both the current user and the supplied
 user or group can see it.  This is due to the implicit 'is:visible'
 clause that is always added by the server.

 is:visible::
 +
 Magical internal flag to prove the current user has access to read
 the change.  This flag is always added to any query.

 starredby:'USER'::
 +
 Matches changes that have been starred by 'USER'.
 The special case `starredby:self` applies to the caller.

 watchedby:'USER'::
 +
 Matches changes that 'USER' has configured watch filters for.
 The special case `watchedby:self` applies to the caller.

 draftby:'USER'::
 +
 Matches changes that 'USER' has left unpublished draft comments on.
 Since the drafts are unpublished, it is not possible to see the
 draft text, or even how many drafts there are. The special case
 of `draftby:self` will find changes where the caller has created
 a draft comment.

 limit:'CNT'::
 +
 Limit the returned results to no more than 'CNT' records.  This is
 automatically set to the page size configured in the current user's
 preferences.  Including it in a web query may lead to unpredictable
 results with regards to pagination.

	== Argument Quoting

	Operator values that are not bare words (roughly A-Z, a-z, 0-9, @,
	hyphen, dot and underscore) must be quoted for the query parser.

	Quoting is accepted as either double quotes
	(e.g. `message:"the value"`) or as matched
	curly braces (e.g. `message:{the value}`).


	== Boolean Operators

	Unless otherwise specified, operators are joined using the `AND`
	boolean operator, thereby restricting the search results.

	Parentheses can be used to force a particular precedence on complex
	operator expressions, otherwise OR has higher precedence than AND.

	=== Negation
	Any operator can be negated by prefixing it with `-`, for example
	`-is:starred` is the exact opposite of `is:starred` and will
	therefore return changes that are not starred by the current user.

	The operator `NOT` (in all caps) is a synonym.

	=== AND
	The boolean operator `AND` (in all caps) can be used to join two
	other operators together. This results in a restriction of the
	results, returning only changes that match both operators.

	=== OR
	The boolean operator `OR` (in all caps) can be used to find changes
	that match either operator. This increases the number of results
	that are returned, as more changes are considered.


	[[labels]]
	== Labels
	Label operators can be used to match approval scores given during
	a code review. The specific set of supported labels depends on
	the server configuration, however the `Code-Review` label is provided
	out of the box.

	A label name is any of the following:

	* The label name. Example: `label:Code-Review`.

	* The label name followed by a ',' followed by a reviewer id or a
	group id. To make it clear whether a user or group is being looked
	for, precede the value by a user or group argument identifier
	('user=' or 'group='). If an LDAP group is being referenced make
	sure to use 'ldap/<groupname>'.

	A label name must be followed by a score, or an operator and a score.
	The easiest way to explain this is by example.

	`label:Code-Review=2`::
	`label:Code-Review=+2`::
	`label:Code-Review+2`::
	+
	Matches changes where there is at least one +2 score for Code-Review.
	The + prefix is optional for positive score values. If the + is used,
	the = operator is optional.

	`label:Code-Review=-2`::
	`label:Code-Review-2`::
	+
	Matches changes where there is at least one -2 score for Code-Review.
	Because the negative sign is required, the = operator is optional.

	`label:Code-Review=1`::
	+
	Matches changes where there is at least one +1 score for Code-Review.
	Scores of +2 are not matched, even though they are higher.

	`label:Code-Review>=1`::
	+
	Matches changes with either a +1, +2, or any higher score.

	`label:Code-Review=+2,aname`::
	+
	Matches changes with a +2 code review where the reviewer or group is aname.

	`label:Code-Review=2,user=jsmith`::
	+
	Matches changes with a +2 code review where the reviewer is jsmith.

	`label:Code-Review=+1,group=ldap/linux.workflow`::
	+
	Matches changes with a +1 code review where the reviewer is in the
	ldap/linux.workflow group.

	`label:Code-Review<=-1`::
	+
	Matches changes with either a -1, -2, or any lower score.

	`is:open label:Code-Review+2 label:Verified+1 NOT label:Verified-1 NOT label:Code-Review-2`::
	+
	Matches changes that are ready to be submitted.

	`is:open (label:Verified-1 OR label:Code-Review-2)`::
	+
	Changes that are blocked from submission due to a blocking score.


	== Magical Operators

	Most of these operators exist to support features of Gerrit Code
	Review, and are not meant to be accessed by the average end-user.
	However, they are recognized by the query parser, and may prove
	useful in limited contexts to administrators or power-users.

	visibleto:'USER-or-GROUP'::
	+
	Matches changes that are visible to 'USER' or to anyone who is a
	member of 'GROUP'. Here group names may be specified as either
	an internal group name, or if LDAP is being used, an external LDAP
	group name. The value may be wrapped in double quotes to include
	spaces or other special characters. For example, to match an LDAP
	group: `visibleto:"CN=Developers, DC=example, DC=com"`.
	+
	This operator may be useful to test access control rules, however a
	change can only be matched if both the current user and the supplied
	user or group can see it. This is due to the implicit 'is:visible'
	clause that is always added by the server.

	is:visible::
	+
	Magical internal flag to prove the current user has access to read
	the change. This flag is always added to any query.

	starredby:'USER'::
	+
	Matches changes that have been starred by 'USER'.
	The special case `starredby:self` applies to the caller.

	watchedby:'USER'::
	+
	Matches changes that 'USER' has configured watch filters for.
	The special case `watchedby:self` applies to the caller.

	draftby:'USER'::
	+
	Matches changes that 'USER' has left unpublished draft comments on.
	Since the drafts are unpublished, it is not possible to see the
	draft text, or even how many drafts there are. The special case
	of `draftby:self` will find changes where the caller has created
	a draft comment.

	limit:'CNT'::
	+
	Limit the returned results to no more than 'CNT' records. This is
	automatically set to the page size configured in the current user's
	preferences. Including it in a web query may lead to unpredictable
	results with regards to pagination.
