Adrien Grand updated LUCENE-7572:
---------------------------------
    Attachment: LUCENE-7572.patch

Here is a patch. DocValuesTermsQuery and DocValuesNumbersQuery now compute a hashCode in constant time. DocValuesTermsQuery was also switched to PrefixCodedTerms to be more consistent with TermsQuery and DocValuesNumbersQuery switched to a hash set of primitive longs to avoid having to box all terms.

> DocValuesNumbersQuery and DocValuesTermsQuery can potentially wrap a large number of terms so it would help if we cached their hashcode.
