I have a Zotero database to which everything gets added. Files are renamed by Zotfile to Author1_Author2_(etal)-Title-Publication-Year.pdf. Zotero generally is pretty good about finding metadata, and there are plugins for full text search. I've probably had as many cases of SciHub serving up the wrong document as Zotero failing to find metadata. I tried recoll, but with the default parameters on my setup the db filled my disk. I think the database was close to 1/15 of indexed disk size. After freeing uo disk space I still use it to find things occasionally, but haven't checked whether the db is updating.
