[ http://issues.apache.org/jira/browse/LUCENE-460?page=comments#action_12356384 ]
paul.elschot commented on LUCENE-460: ------------------------------------- > - hash codes should strive to be unique across the Query hierarchy, not just > unique within one specific > subclass. For example, TermQuery(t) and SpanTermQuery(t) will generate the > exact same hash codes. This has the disadvantage that the structure information added by the query parser is lost in the hash. In case a hash is needed over the query text before parsing, one can use precisely that. What's the point of hash code uniqueness over subclasses?
