------------------------------------------
Summary: Add DocValuesNumbersQuery, like DocValuesTermsQuery but
works only with long values
Key: LUCENE-6539
URL: https://issues.apache.org/jira/browse/LUCENE-6539
Project: Lucene - Core
Issue Type: New Feature
Reporter: Michael McCandless
Assignee: Michael McCandless
Fix For: Trunk, 5.3
This query accepts any document where any of the provided set of longs
was indexed into the specified field as a numeric DV field
(NumericDocValuesField or SortedNumericDocValuesField). You can use
it instead of DocValuesTermsQuery when you have field values that can
be represented as longs.
Like DocValuesTermsQuery, this is slowish in general, since it doesn't
use an inverted data structure, but in certain cases (many
terms/numbers and fewish matching hits) it should be faster than using
TermsQuery because it's done as a "post filter" when other (faster)
query clauses are MUST'd with it.
In such cases it should also be faster than DocValuesTermsQuery since
it skips having to resolve terms -> ords.
