 The `S` or `start` query parameter can be supplied to skip a number
 of changes from the list.
 
+Administrators can use the `skip-visibility` query parameter to skip visibility filtering.
+This can be used to ensure that no changes are missed e.g. when querying for changes which
+need to be reindexed. Without this parameter query results the user has no permission to read
+are filtered out. REST requests with the skip-visibility option are rejected when the current

 Clients are allowed to specify more than one query by setting the `q`
 parameter multiple times. In this case the result is an array of
 arrays, one per query in the same order the queries were given in.

+# Incremental reindexing during upgrade of large gerrit site
+
+In order to shorten the downtime needed to reindex changes during a
+Gerrit upgrade the following strategy can be used:
+
+- index preparation
+  - create a full consistent backup
+  - note down the timestamp when the backup was created (backup-time)
+  - create a complete copy of the production system from the backup
+  - upgrade this copy to the new Gerrit version
+  - online reindex this copy
+- upgrade of the production system
+  - make system unavailable so that users can't reach it anymore
+    e.g. by changing port numbers (downtime starts)
+  - take a full backup
+  - run
+
+    ``` bash
+    ./reindex.py -u gerrit-url -s backup-time
+    ```
+
+    to write the list of changes which have been created or modified
+    since the backup for the index preparation was created to a file
+    "changes-to-reindex.list"
+  - upgrade the production system to the new gerrit version skipping
+    reindexing
+  - copy the bulk of the new index from the copy system to the
+    production system
+  - run
+
+    ``` bash
+    ./reindex.py -u gerrit-url
+    ```
+
+    this reindexes all changes which have been created or modified after
+    the backup was taken reading these changes from the file
+    "changes-to-reindex.list"
+  - smoketest the system
+  - make the production system available to the users again
+    (downtime ends)
+
+## Online help
+
+For help on all available options run
+
+``` bash
+./reindex -h
+```
+
+## Python environment
+
+Prerequisites:
+
+- python 3.9
+- pipenv
+
+Install virtual python environment and run the script
+
+``` bash
+pipenv sync
+pipenv shell
+./reindex <options>
+```
