This question already has an answer here:
I mean the topics which I have started. That is, whole topics, not my posts only.
For example, a situation when someone answers my question some time ago, but since then I have forgotten the whole thing, but remember some words from that answer. I could spend a day walking across my posts. Also I know that I can put a filter for particular user, here
user:me, but in this case I would only find my text.
The situation that arose here so I'm asking this is that I remember someone answering for a unrelated question gave me a tip of useful GCC parameters additional to
-Wall. I didn't asked for it so I don't know in what topic to look for it and who was that. Now I must search all my topics for this keyword, but exclude my own writing.
