To date, email search has always been exact match or part match/typo keyword based. It would be amazing if you could run an AI search for anything related to the item. Eg. if i was to search "company + hosting quote" and the actual wording in the email was "company + server proposal" then it would still bring up the result.

Or (provided it's secure and not training OpenAI...) search for topics like "complaint emails from last year"
