I haven't tried it yet, but I'm glad to know that option is there, so thanks anyway. It wasn't a waste. I never noticed that option.

Sorry, Rita, I decided it wouldn't really be of much help to you and deleted it, but I kinda forgot that you'd get it anyway. Oops!
What I do is search for as unique a word/term/phrase as I can think of in the body of the post and that, combined with remembering who posted, generally finds me what I'm looking for; I've never had much success if I didn't remember whose post I was looking for. And don't forget to put your search term in quotes if you're certain you've got it right.
