Mail 6.2 in Mountain Lion-Irrelevant Search Results Show Up

Question

Hi Mail(.app)ers,
I use Mail.app (version 6.2) on Mountain Lion, with one email account—my Google Apps email—via IMAP, with all folders (aka "mailboxes) synchronized with the Google servers—i.e. nothing exclusively on my local machine—with the exception of my "Drafts" folder. There are something like 12,000 emails altogether.
Anyway… I use the search bar a lot, and I'm getting this peculiar thing where a word I type will display a list of all emails containing that word, as per usual, but the list also has some emails that don't have that word in it, or in the headers. When I search within an email that shows up on the list for the exact word that produced it as a result for containing that word, there are zero results. It's not a terrible deal, but an annoyance, and these discussions are full of things that aren't terrible but are annoyances. Anyway… just wondering… does this happen with anyone else?

Answer 1

Thanks. No dice though, same with rebuilding the mailbox. It's the IMAP boxes that are messed up—just the "Trash - Gmail," "Sent - Gmail," and "Inbox - Gmail," whereas  the 9 folders that I've made are fine.
