Serious Fulltext Search Limitations

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

The fulltext search allows you to search for things containing a given search term.

What is missing:

• parts of the entered search term are always combined by disjunction - there is no hint to how (if so) you can combine by conjunction,
• constraints to restrict search to a given folder (when its about files, but actually, when its about "fulltext" - you realize the mess when you understand this, right???)

Steps to reproduce

1. search
2. fulltext
3. whatever

The report names no files, tests, or entry points; begin by locating the full-text search implementation and how it handles query terms and folder scope. Done would require a clear, reproducible decision for conjunction and folder constraints, with coverage for the agreed behavior.
