Declutter search bar to only show search query

This commit changes the way search filters are parsed. Instead of
directly appending the data into the search query and creating k:v
pairs, all of the search filters are now a URL parameter. This results
in a clear look overall and hides much of the logic from the end user.

Closes #1969
