The problem is totally the same as [Search not working: “added:” returns more results than expected]
“huge card IDs” solution and its “add-on” (196231552) don’t work
It sounds like you’re talking about: Search not working: "added:" returns more results than expected . That discussion is about Anki 2.1.54 from over 2 years ago, and referencing another version over 3 years ago. Are you still using 2.1.54?
You haven’t told us anything about what is happening for you, what got you into the situation, or which part of those threads is “totally the same” – so it’s hard to suggest solutions for you. You also don’t say what didn’t work about that fix(es) in those threads – which appear to be mostly invisible changes.
