3 fix typeahead searchbar b

fixes all the remaining issues with typeahead search bar including:
1) searching searches first and last name now
2) if you search for things with whitespace, the query takes the terms and basically OR's them (now the query 'Amy Zhang' will work as expected but this could have some unintuitive behavior. thoughts?)
3) no ugly json when you select an item
4) clicking with a mouse on the menu now works.
