    @Deprecated
    public static enum Field.Index

extends Enum<Field.Index>

Specifies whether and how a field should be indexed.

Enum Constant Summary
`ANALYZED` Deprecated. Index the tokens produced by running the field's value through an Analyzer.
`ANALYZED_NO_NORMS` Deprecated. Expert: Index the tokens produced by running the field's value through an Analyzer, and also separately disable the storing of norms.
`NO` Deprecated. Do not index the field value.
`NOT_ANALYZED` Deprecated. Index the field's value without using an Analyzer, so it can be searched.
`NOT_ANALYZED_NO_NORMS` Deprecated. Expert: Index the field's value without an Analyzer, and also disable the indexing of norms.

Enum Constant Detail

### NO

    public static final Field.Index NO

  Deprecated.
  Do not index the field value. This field can thus not be searched, but one can still access its contents provided it is `stored`.

### ANALYZED

    public static final Field.Index ANALYZED

  Deprecated.
  Index the tokens produced by running the field's value through an Analyzer. This is useful for common text.

### NOT_ANALYZED

    public static final Field.Index NOT_ANALYZED

  Deprecated.
  Index the field's value without using an Analyzer, so it can be searched. As no analyzer is used the value will be stored as a single term. This is useful for unique Ids like product numbers.

### NOT_ANALYZED_NO_NORMS

    public static final Field.Index NOT_ANALYZED_NO_NORMS

  Deprecated.
  Expert: Index the field's value without an Analyzer, and also disable the indexing of norms. Note that you can also separately enable/disable norms by calling `FieldType.setOmitNorms(boolean)`. No norms means that index-time field and document boosting and field length normalization are disabled. The benefit is less memory usage as norms take up one byte of RAM per indexed field for every document in the index, during searching. Note that once you index a given field with norms enabled, disabling norms will have no effect. In other words, for this to have the above described effect on a field, all instances of that field must be indexed with NOT_ANALYZED_NO_NORMS from the beginning.

### ANALYZED_NO_NORMS

    public static final Field.Index ANALYZED_NO_NORMS

  Deprecated.
  Expert: Index the tokens produced by running the field's value through an Analyzer, and also separately disable the storing of norms. See `NOT_ANALYZED_NO_NORMS` for what norms are and why you may want to disable them.

Method Detail

### values

    public static Field.Index[] values()

  Deprecated.
  Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

      for (Field.Index c : Field.Index.values())
          System.out.println(c);

  Returns:
    an array containing the constants of this enum type, in the order they are declared

### valueOf

    public static Field.Index valueOf(String name)

  Deprecated.
  Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

  Parameters:
    `name` - the name of the enum constant to be returned.
  Returns:
    the enum constant with the specified name
  Throws:
    `IllegalArgumentException` - if this enum type has no constant with the specified name
    `NullPointerException` - if the argument is null

### toIndex

    public static Field.Index toIndex(boolean indexed,
                                      boolean analyzed)

  Deprecated.
  Get the best representation of the index given the flags.

### toIndex

    public static Field.Index toIndex(boolean indexed,
                                      boolean analyzed,
                                      boolean omitNorms)

  Deprecated.
  Expert: Get the best representation of the index given the flags.

### isIndexed

    public abstract boolean isIndexed()

  Deprecated.

### isAnalyzed

    public abstract boolean isAnalyzed()

  Deprecated.

### omitNorms

    public abstract boolean omitNorms()

  Deprecated.
