If Prophet's Advanced Search isn't working or gives an error that it needs to be rebuilt, please contact Support with this error.
This might also happen from an open Opportunity, after you click the Companies button and there are none showing.
If you have any questions, please call Avidian Prophet Technical Support at 855-284-3426 x2.
Or you can email Support@Avidian.com.
Rebuild the customer's database's Full-Text Indexes.
And run IndexAllRebuild.sql.
If those don't fix it, notably for the Company Search, see details in https://gitlab.com/avidian-technologies/prophet/-/issues/765#note_1031929442
