## Class SortedSetDocValuesField

- java.lang.Object
- - org.apache.lucene.document.Field
  - - org.apache.lucene.document.SortedSetDocValuesField

- All Implemented Interfaces:
    IndexableField

      public class SortedSetDocValuesField
      extends Field

  Field that stores a set of per-document `BytesRef` values, indexed for faceting,grouping,joining. Here's an example usage:

         document.add(new SortedSetDocValuesField(name, new BytesRef("hello")));
         document.add(new SortedSetDocValuesField(name, new BytesRef("world")));

  If you also need to store the value, you should add a separate `StoredField` instance.

  Each value can be at most 32766 bytes long.

- - ### Field Detail

    - #### TYPE

          public static final FieldType TYPE

      Type for sorted bytes DocValues

  - ### Constructor Detail

    - #### SortedSetDocValuesField

          public SortedSetDocValuesField(String name,
                                         BytesRef bytes)

      Create a new sorted DocValues field.
      Parameters:
        `name` - field name
        `bytes` - binary content
      Throws:
        `IllegalArgumentException` - if the field name is null

  - ### Method Detail

    - #### newRangeQuery

          public static Query newRangeQuery(String field,
                                            BytesRef lowerValue,
                                            BytesRef upperValue,
                                            boolean lowerInclusive,
                                            boolean upperInclusive)

      Create a range query that matches all documents whose value is between `lowerValue` and `upperValue`.

      This query also works with fields that have indexed `SortedDocValuesField`s.

      NOTE: Such queries cannot efficiently advance to the next match, which makes them slow if they are not ANDed with a selective query. As a consequence, they are best used wrapped in an `IndexOrDocValuesQuery`, alongside a range query that executes on points, such as `BinaryPoint.newRangeQuery(java.lang.String, byte[], byte[])`.

    - #### newExactQuery

          public static Query newExactQuery(String field,
                                            BytesRef value)

      Create a query for matching an exact `BytesRef` value.

      This query also works with fields that have indexed `SortedDocValuesField`s.

      NOTE: Such queries cannot efficiently advance to the next match, which makes them slow if they are not ANDed with a selective query. As a consequence, they are best used wrapped in an `IndexOrDocValuesQuery`, alongside a range query that executes on points, such as `BinaryPoint.newExactQuery(java.lang.String, byte[])`.
