## Class DocValuesNumbersQuery

- java.lang.Object
- - org.apache.lucene.search.Query
  - - org.apache.lucene.search.DocValuesNumbersQuery

- All Implemented Interfaces:
    Accountable

      public class DocValuesNumbersQuery
      extends Query
      implements Accountable

  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.

  WARNING: This API is experimental and might change in incompatible ways in the next release.
