## Interface IndexableFieldType

- All Known Implementing Classes:
    FieldType

      public interface IndexableFieldType

  Describes the properties of a field.
  WARNING: This API is experimental and might change in incompatible ways in the next release.

- - ### Method Summary

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method and Description
    --- | ---
    `DocValuesType` | `docValuesType()` DocValues `DocValuesType`: how the field's value will be indexed into docValues.
    `IndexOptions` | `indexOptions()` `IndexOptions`, describing what should be recorded into the inverted index
    `boolean` | `omitNorms()` True if normalization values should be omitted for the field.
    `int` | `pointDimensionCount()` If this is positive, the field is indexed as a point.
    `int` | `pointNumBytes()` The number of bytes in each dimension's values.
    `boolean` | `stored()` True if the field's value should be stored
    `boolean` | `storeTermVectorOffsets()` True if this field's token character offsets should also be stored into term vectors.
    `boolean` | `storeTermVectorPayloads()` True if this field's token payloads should also be stored into the term vectors.
    `boolean` | `storeTermVectorPositions()` True if this field's token positions should also be stored into the term vectors.
    `boolean` | `storeTermVectors()` True if this field's indexed form should be also stored into term vectors.
    `boolean` | `tokenized()` True if this field's value should be analyzed by the `Analyzer`.

- - ### Method Detail

    - #### stored

          boolean stored()

      True if the field's value should be stored

    - #### tokenized

          boolean tokenized()

      True if this field's value should be analyzed by the `Analyzer`.

      This has no effect if `indexOptions()` returns IndexOptions.NONE.

    - #### storeTermVectors

          boolean storeTermVectors()

      True if this field's indexed form should be also stored into term vectors.

      This builds a miniature inverted-index for this field which can be accessed in a document-oriented way from `IndexReader.getTermVector(int,String)`.

      This option is illegal if `indexOptions()` returns IndexOptions.NONE.

    - #### storeTermVectorOffsets

          boolean storeTermVectorOffsets()

      True if this field's token character offsets should also be stored into term vectors.

      This option is illegal if term vectors are not enabled for the field (`storeTermVectors()` is false)

    - #### storeTermVectorPositions

          boolean storeTermVectorPositions()

      True if this field's token positions should also be stored into the term vectors.

      This option is illegal if term vectors are not enabled for the field (`storeTermVectors()` is false).

    - #### storeTermVectorPayloads

          boolean storeTermVectorPayloads()

      True if this field's token payloads should also be stored into the term vectors.

      This option is illegal if term vector positions are not enabled for the field (`storeTermVectors()` is false).

    - #### omitNorms

          boolean omitNorms()

      True if normalization values should be omitted for the field.

      This saves memory, but at the expense of scoring quality (length normalization will be disabled), and if you omit norms, you cannot use index-time boosts.

    - #### indexOptions

          IndexOptions indexOptions()

      `IndexOptions`, describing what should be recorded into the inverted index

    - #### docValuesType

          DocValuesType docValuesType()

      DocValues `DocValuesType`: how the field's value will be indexed into docValues.

    - #### pointDimensionCount

          int pointDimensionCount()

      If this is positive, the field is indexed as a point.

    - #### pointNumBytes

          int pointNumBytes()

      The number of bytes in each dimension's values.
