Robert Muir commented on SOLR-219:
----------------------------------
Mike I don't totally understand the question: in general there are only several
categories of queries supported by the queryparser:
* Core queries like Term, Phrase, SloppyPhrase, MultiPhrase: these go thru the
analyzer.
* MultiTermQueries like WildcardQuery, PrefixQuery, FuzzyQuery, RegexpQuery,
which are patterns that rewrite against the term index into some simpler form
(e.g. into TermQueries)
If you were to write an AnagramQuery, you would first have to add queryparser
support anyway to it. But, if you want anagrams you could just write an anagram
tokenfilter that sorts the characters in the termbuffer: then you wouldn't need
to write a custom query, nor custom queryparser integration, and it would be
fast.
