Fulltext search

Hi,

I’ve RT 5.0.3 from debian bookworm, postgres database. I inicialize fulltext search ( Full text indexing - RT 5.0.3 Documentation - Best Practical ), table attachmentsindex include data, fulltext is configured in SiteConfig. But search from RT interface show 0 results. There are errors in debug.log:
NOTICE: text-search query contains only stop words or doesn’t contain lexemes, ignored (/usr/share/perl5/DBIx/SearchBuilder/Handle.pm:622)

I don’t use stopwords (there are no common words in search).

If I disable index in SiteConfig.pm, search is working, but too slow.

Do you have any idea to solve/track this issue? I tried upgrade to 5.0.7 (newest in debian), but without success.
