meanwhile, From:name appears to work when searching for a lowercase first name.
this is despite one of the suggested searches containing an all lowercase from:me example.

This is very likely due to the fact that

• The from:whatever syntax prioritizes user whatever if it exists, and otherwise does fuzzy search (see this), and
• There actually is a user with username tim (see here) :-)

I'm looking at other weirdnesses with from:whatever searches, and will keep this ticket in mind if/when I (hopefully) submit a patch to address them.
