Indexing User
The indexer runs as a background job, usually with no user associated with it. For pages whose title are computed by a "sheet" document the computed title will not show up if the sheet is not visible for anonymous users. This is especially the case if the wiki is closed. In that case e.g. search results for user profiles are not shown with their computed title «Profile of "firstname" "lastname"», but just their page name (usually «login»).
To be able to show the same title in the search results it is necessary to provide the indexer with a user who has access to the sheet pages. It is recommended to create a dedicated, locked user account without special rights.
Changes to this setting are applied only to pages indexed after the change; a full reindex is recommended for consistent application of the change.
