TMDQ may take a long time when trying to create a page of results with a sparse result set. You can limit the time Alfresco Content Services spends per TMDQ query by configuring a maximum duration or a maximum number of permission checks before returning. Setting this limit increases search speed and reduces the use of resources but may result in the user receiving a partial page of results for expensive queries.

You can limit both the time spent and the number of documents checked before Alfresco Content Services returns search results using the system.acl.maxPermissionCheckTimeMillis and the system.acl.maxPermissionChecks properties. The default values are 10000 and 1000 respectively.

  1. Open the <classpathRoot>/alfresco-global.properties file.
  2. Set the system.acl.maxPermissionCheckTimeMillis property.

    For example, system.acl.maxPermissionCheckTimeMillis=20000.

  3. Set the system.acl.maxPermissionChecks property.

    For example, system.acl.maxPermissionChecks=2000.

    Note: If you increase these values and have a query that returns a very large number of results, (a) the search results will take longer to be returned to the user, and (b) the system will spend longer to check permissions, leading to the possibility of performance degradation. If you set these values to a low number, you run the risk of inconsistent search results every time you run the same search. These settings are also applied when paging. So paging the results will only go up to the maximum returned results based on these settings.
