jabref: JabRef freezes when trying to search

JabRef version
JabRef 5.4–2021-07-24–1cdd807 Linux 5.4.0-80-generic amd64 Java 16.0.1 JavaFX 16+8
[ x] Mandatory: I have tested the latest development version from http://builds.jabref.org/main and the problem persists
Steps to reproduce the behavior:
start program
type the first five chars of a search string
JabRef freezes, or goes to sleep.
The System Monitor (top) shows 1.3GB of memory being used by JabRef,
and also the full resources of several processors (no other active tasks):

Yes, search button behaviour is now as expected.
I cannot generate a freeze any more. Yay!
wujastyk on Aug 30, 2021
Yes, when fulltext works, I do see the “search results”.
I now cannot reproduce the freezing at will on my laptop. On my desktop, yes, freezing continues to be a problem.
wujastyk on Aug 21, 2021
Wow, so fulltext searches all my linked files! I had no idea. That’s a big task. grep -c file bibfile.bib shows 1235 linked PDFs in my main bib file. But there are 7000 in the same directory tree. JabRef wouldn’t search them too, I hope.
wujastyk on Aug 20, 2021
I would recommend also sending along the preferences. I suggest that because in a case with search & crashes I traced the issue back to preference settings.
ilippert on Aug 17, 2021
It’s a chicken and egg thing. If I start a search, the program freezes and I can’t open the log. If I don’t do a search, the log is empty.
wujastyk on Aug 16, 2021
Yes, I now see the background-progress-status-indicator. Sorry for being so stupid, everyone 😃
But I can’t click it to see what’s happening, because as soon as I start typing a search, everything freezeees.
wujastyk on Aug 15, 2021
If an item in the toolbox is not displayed because the window is too small, at least a chevron should show with a context menu providing the hidden toolbar buttons
calixtus on Aug 12, 2021
Hi, not asked, but still providing. I have +10k entries with say 1k files linked. I have no idea for how long to wait for the indexing to be done as there is no percentage given 😉 (that would probably count as an improvement)
Your right, that would count as an improvement 😉 #7981
I cannot reproduce the error anymore reliably
Good news. But what do you mean reliably? Does it still happen from time to time?
