I often might recall a date or couple words, but forget when or who that was with. And my suggestion still applies to ALL conversations as opposed to other Ideas related to single conversation, but that difference is a checkbox away from satisfying both asks. For example, I searched for Dec 1, and it found anything that had DEC in it, even within a word, and everything with a 1. Well that is a LOT of stuff and not at all helpful for my need. Can you add the quote tactic where anything in quotes, like "Dec 1" looks only for that exact string? Taking it a step further you could have options for exact case, or fuzzy logic for variants, but as a minimum / default use Any Case matching the exact characters as the default. I might not have remembered the captilizaton used, especially if it was the start of a sentence or not.
