Well "fuzzy" is not really well defined. Lucene defines it as Levenshtein
Distance, or Edit Distance. In the spec I think fuzzy should just mean "try
harder than stemming", so in my eyes soundex would be valid.

distance - not sure what this is?


Check if two words occur within a given distance (in words) of each other.

tracker also supports :

Well, I think we need a poll or something :-)

StartsWith, <=, and >= should probably be standard (?),  I don't know about
regexp though... I don't think Lucene can do it for instance.

Maybe we need a base set of supported selectors, and then have optional ones
you can query with  a GetExtendedSelectors() method or something.

otherwise looking good :)


Super.

Another thing that is not covered in the current spec is what to do with
wildcards. Cheers,

Mikkel
