public class QueryFilters
extends Object

Creates and caches QueryFilter implementing plugins. QueryFilter implementations should define either the "fields" or "raw-fields" attributes for any fields that they process, otherwise these will be ignored by the query parser. Raw fields are parsed as a single Query.Term, including internal punctuation, while non-raw fields are parsed containing punctuation are parsed as multi-token Query.Phrase's.
