Model Manager uses a specialized search index when searching and filtering item versions. Under normal program execution, Model Manager automatically pushes any updates made to items in the database to this search index, both for a local database and for a server database. This push may fail, however — for a Model Manager server, for example, due to intermittent network issues when the Model Manager server process tries to communicate with the process managing the search index.

You can manually trigger the push of changes to the search index, thereby letting the search index catch up with any changes made in the database. Right-click a database node in The Databases Tree and select Index () to push changes made on all branches. Do the same for a branch node to only push changes made on that branch.
