Enum FieldInfo.IndexOptions

    • Enum Constant Detail

      • DOCS_ONLY

        public static final FieldInfo.IndexOptions DOCS_ONLY
        Only documents are indexed: term frequencies and positions are omitted. Phrase and other positional queries on the field will throw an exception, and scoring will behave as if any term in the document appears only once.
      • DOCS_AND_FREQS

        public static final FieldInfo.IndexOptions DOCS_AND_FREQS
        Only documents and term frequencies are indexed: positions are omitted. This enables normal scoring, except Phrase and other positional queries will throw an exception.
      • DOCS_AND_FREQS_AND_POSITIONS

        public static final FieldInfo.IndexOptions DOCS_AND_FREQS_AND_POSITIONS
        Indexes documents, frequencies and positions. This is a typical default for full-text search: full scoring is enabled and positional queries are supported.
      • DOCS_AND_FREQS_AND_POSITIONS_AND_OFFSETS

        public static final FieldInfo.IndexOptions DOCS_AND_FREQS_AND_POSITIONS_AND_OFFSETS
        Indexes documents, frequencies, positions and offsets. Character offsets are encoded alongside the positions.

      • values

        public static FieldInfo.IndexOptions[] values()
        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 (FieldInfo.IndexOptions c : FieldInfo.IndexOptions.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static FieldInfo.IndexOptions valueOf​(String name)
        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
