I have a working setup (on fuseki 3.14) where I can see different results
using AND/OR, and where "~" fuzzy operator also works.
Differences from your config seem to be that I haven't configured much for
the index, only the directory and entity map. Would testing if a minimal
config works and then rebuilding index from command line, with more
configuration each time until it breaks help?
<#text_index> a text:TextIndexLucene ; text:directory
</var/fuseki/databases/place-name-data/Lucene> ; text:entityMap
<#entMap> ; .
Best regards,
Øyvind
