Search by meaning, not just words
Search matches chats and files by what they mean as well as the words they contain, so the right one turns up when you only remember the gist.
What it includes
Word matches first
Exact word matches appear at once, and matches by meaning join the list a moment later without holding it up.
Recent work ranks higher
Recently active chats get a boost, so this month's discussion outranks an old thread on the same subject.
Always answers
When matching by meaning is slow or unavailable, search answers from the words alone rather than hanging.
