Group queries only match internal groups. External groups and system groups are not included in the query result.
Similar to many popular search engines on the web, just enter some text and let Gerrit figure out the meaning:
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, which will match against a variety of fields.
Matches groups that have a description that contains DESCRIPTION (case-insensitive).
Matches groups that have a name part that starts with NAMEPART (case-insensitive).
Matches groups that are in the groups options marked as visible to all registered users.
Matches groups that have the name NAME (case-insensitive).
Matches groups that are owned by the group whose name best matches OWNER or that has the UUID OWNER.
Matches groups that have the UUID UUID.
Matches groups that have the account represented by MEMBER as a member.
Matches groups that have a subgroup whose name best matches SUBGROUP or whose UUID is SUBGROUP.
Magical internal flag to prove the current user has access to read the group. This flag is always added to any query.
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.
