Feature Request: ambar.cloud Search integration

Hi there! Thanks for your great work on this Addon!

Unfortunally the search is very inaccurate. For example, in my company we have documents with customer IDs like P#9234v which are added to the paper with a label sticker and get scanned after that with OCR as PDF. The Fulltext Search in nextcloud gets confused with this and find nothing. I also had a look into the elasticsearch server itself with the tool Dejavu and tried to find the id there - no success.

after some googleing i found the tool ambar.cloud. I made a little proof of concet setup with installing ambar cloud and give it the data source dir as webdav mountpoint on the machine. the search results are amazing! I wish this quality of search results were built in to nextcloud! :)

I'm not a developer, just a linux admin - but maybe someone has the mood and time to have a look to ambar.cloud and find a way to integrate it with nextcloud? that would be fantastic! :)

For now my workaround is an ambar.cloud instance for my colleagues - but its not very handy but good for now :)

Best regards from Berlin!

The issue names no repository files, tests, or entry points. Start by reviewing the existing full-text search and Elasticsearch integration, then compare its behavior with the reported ambar.cloud results and define a concrete integration scope and acceptance criteria.
