Changes have ben made to the search server, but we need the mbserver to now remove its busines logic and make the appropriate call, and then deployed onto test.musicbrainz.org asap so changes can be tested

Needs changes in https://github.com/metabrainz/musicbrainz-server/blob/master/lib/MusicBrainz/Server/Data/Search.pm:

Remove escape_query and alias_query and calls to them
For basic search just pass raw query to search server with extra paramater dismax=true
