Re-indexing Search Server Did Not Resolve Issues with Viewing Projects, Workbooks, and/or Views

Issue

Projects, Workbooks, and/or Views are not visible in the Tableau Server UI, even after running a tsm maintenance reindex-search command

After attempting to reindex the search log lines similar to the below may appear:

Environment

Tableau Server

Resolution

Ensure Tableau Server is licensed as expected. Go to TSM either the UI or the command line, and verify the licenses are activated as expected. If licenses are not activated as expected, add the licenses back or contact Technical Support before continuing with the next steps.
Run tsm stop
Once Tableau Server is fully stopped, you may wish to take a backup. While we don't expect anything we do here to cause issues for the system, it is always best practice to ensure there is a current backup.
Reset the Searchserver by running: tsm maintenance reset-searchserver.
After that command finishes, we'll want to bring the server back up with tsm start.

If the above steps does not resolve the issue, contact Tableau Technical Support.

Cause

This issue appears to occur because of a corruption to the underlying searchserver index. This can occur during an unexpected reboot, after system upgrades, etc. The tsm maintenance reset-searchserver command gets rid of the old index and completely rebuilds it.
