This nostr search tool by @NotBiebs is still one of my favorite ways to search for notes. I was able to find one I posted over a year and a half ago relatively easily by narrowing it down within a date range.

 @jb55 wen search on profile pages in Damus? 

 proper nip50 support in nostrdb is needed first, then we would be able to combine our fulltext search with other filters. Shouldn’t be too difficult.
