Is it possible to do a search in the comment sections like we with discussions?

One day I started a discussion about google AdWords and the next day I saw an answer that had nothing to do with my discussion. They gave the URL of a site and were asking to sign under them. So I answered the person and told then that their answer wasn't related to my question. Well afterwards I went to see again my list of the discussions that I started and to my horror I see there is 0 answers! I Freaked out! I commented on somebody's discussion! I looked into the discussions I answered and I couldn't find where I commented! I wanted to find where I made the wrong comment so that I can explain myself to people. Do you think we can do a search on the comment sections on mylot? If not do you think it would be helpful if they could add this feature?
