Sure. I can't aways remember the specific thing I was trying to search for but something along these lines
  • phrase search - for instance, say I was searching for an article that had the exact phrase "seedsigner vs ledger". I know I saw it. Can't find it now, can't search for this as an exact phrase.
  • date range search - I posted something with a different login. I know WHEN I posted it, but don't have my login anymore. If I could search on a date range, I could find it, just by looking at everything in that date range
  • negative search - I wanted to do a search for.... okay I can't remember exactly what I was searching for, but I was trying to search for a word that has 2 meanings, I only wanted one of those meanings, so I would have liked to "subtract" out the unwanted meaning**. It's the "none of these words" search on google (https://www.google.com/advanced_search)
  • ordering only, no search - recently I wanted to just poke around and see what, over time, had the highest ranking (sats, zapranks, etc). Not really a search, but just an ordering of EVERYTHING, by sats. I ended up just throwing the word "bitcoin" in the search box, just to be able to run the search. But I really wanted to see everything in the order I wanted, not just bitcoin-related posts.
Another thought - what about searching in the title only, not the whole content?
In terms of priorities - for me the priority would be a phrase search. I use that all the time in other search engines, it's really handy.
