There should be more details in the Eclipse log. Please post the log entry including the exception stack trace. The Eclipse log file is in your workspace in folder .metadata.

Thanks a lot! Log entry (which re-occurs per use of File Search) is quite meaningful.

Have now tried to download a fresh copy of 2021-12 using the existing workspace: same symptom, although I have noticed that the File Search option "Selected resources" does not throw the exception, just "Workspace" and "Enclosing projects".
Have tried to open another (existing) workspace confirming the workspace migration dialog. There File Search works without throwing an exception. So the symptom seems to be related with the workspace that was migrated tpgether with the IDE.
Have created a new workspace, in there created a new (PHP) project and imported the artifacts of the migrated workspace. This works around the issue. File Search is again functional. So the issue seems to be related with migrating a workspace containing PHP projects, as the Java workspace migrated in comment #5 was not affected.

Please make sure that you have org.eclipse.search in 3.14.100 or better in your environment available. *** This bug has been marked as a duplicate of bug 577741 ***
Indeed, the latest STS contains org.eclipse.search_3.14.0.v20211108-0804.jar. I will wait for the next update and see if it's fixed.
