Regular expression in search field and group delivers strange results

[ytzemih]

JabRef version

Latest development branch build (please note build date below)
I tried the build from 2024-11-05 23:12

Operating system

GNU / Linux

Details on version and operating system

Linux Mint/Debian 12

Checked with the latest development build (copy version output from About dialog)

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

1. Use, for example, a complex search expression "(title = a|b|c) or (keywords = d|e|f)", which works just fine for me under JR 5.15, either in the search field or as an expression in some search group.
2. Make sure "regular expression" checkbox/feature is turned on.
3. You get an empty result or at least a result that does not include entries expected to be included.
4. (optional) When changing the search expression a few times (extend it, correct, etc.), the entry list slowly degrades: the filter seems to fail to update properly and empty entries appear. Scrolling makes everything worse.
   There are perhaps several issues at play. But my focus was on getting a search done. The migration back to the old (nice) search seems not to be a faithful migration. I discovered these issues after migrating the search expressions from 5.16 back to the old search. Thanks for checking this.

I have switched back to JR 5.15 and the back-migrated search expressions work pretty well again.
