How to do activate true full text search? Or how to modify solr request?

[mosea3]

Hi guys,

I seem to have issues with the latest OSS of 04.2024, it doesnt seem to do real full text search.

My use case: index PDF documents with OCR text layer into OSS. So Tika extracts the content and the ETL python program sends it to Solr into the Document field content_txt.

Sadly, searching for some partial content in content_txt doesnt return the document, even if literal match. Searching for main document attributes (title) works.

Is it possible to modify the Solr request so that I can find also by any string match? Right now by default, the request seems to just be the bare content of $_GET['q'] the q value of the searchfield.

Thanks for you help!
