>                 Key: MBS-234
>                 URL: http://jira.musicbrainz.org/browse/MBS-234
>             Project: MusicBrainz Server
>          Issue Type: Improvement
>    Affects Versions: NGS - Beta 2
>            Assignee: Paul Taylor
>
> I think the current artist search runs
> artist:(x)(sortname:(x) alias:(x) !artist:(x))
> where x is the search term entered.
> Suffers from two problems:
> 1. Equals precedence is given to an alias or sortname match to an artist match.
> 2. It doesn't have to match phrases just individual words in an artist name.
> Would get better results with the following
> artist:"x"^5 sortname:"x"^4 (artist:x^3 sortname:x^2 AND NOT artist:"x" AND NOT sortname:"x") (alias:x AND NOT artist:x AND NOT sortname:x)
> i.e
> artist:"queen"^5 sortname:"queen"^4 (artist:queen^3 sortname:queen^2 AND NOT artist:"queen" AND NOT sortname:"queen") (alias:queen AND NOT artist:queen AND NOT sortname:queen)
> actually a one field artist like queen could be simplified to
> artist:x^3 sortname:x^2  (alias:x AND NOT artist:x AND NOT sortname:x)
> So this favours in order:
> Full word match on Artist
> Full word match on Sortname
> Word match on Artist
> Word match on Sortname
> Word match on Alias
