The database index was cleared with the new version install. We are aware of the problem and it wil be adressed in the next PDAS development cycle. The problem is updates often change the database structure so there is currently a need to reset it.
You need to fast-import document to the database again. You can fast-import document from the storage (just first move them elsewehere) but you will lose original names. Or you can import original documents.
Fast import is performed through PDAS control center > Document Manager > Add Document and is way faster then adding document through PDC.
We are sorry for the curent inconvenience.
