Tracy said she wanted a list of all her own messages by month. This accomplishes that. Your request is asking for something entirely different, and I'm afraid don't have an answer for that.

Now that I think about it, if Michel provided an option to exclude words as well as the options of included words and exact phrase, then you could search your own ID and exclude the word 'Re:' since no new threads include the word 're' in the subject. That might be a simpler option for Michel than a whole new type of search.
