Class DocValuesNumbersQuery

java.lang.Object

org.apache.lucene.search.Query

org.apache.lucene.search.DocValuesNumbersQuery

All Implemented Interfaces:

Cloneable

public class DocValuesNumbersQuery
extends Query

Like 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.
