public class DocValuesNumbersQuery extends Query
DocValuesTermsQuery
, but this query only
runs on a long NumericDocValuesField
or a
SortedNumericDocValuesField
, matching
all documents whose value in the specified field is
contained in the provided set of long values.
NOTE: be very careful using this query: it is
typically much slower than using TermsQuery
,
but in certain specialized cases may be faster.

works properly.
Typically a query will be equal to another only if it's an instance of
the same class and its document-filtering properties are identical that other
instance. Utility methods are provided for certain repetitive code.equals
