All Implemented Interfaces:

IndexableField

public class SortedBytesDocValuesField
extends Field

Field that stores a per-document BytesRef value, indexed for sorting. Here's an example usage:

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

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

Field Detail

TYPE_FIXED_LEN

Type for sorted bytes DocValues: all with the same length

TYPE_VAR_LEN

public static final FieldType TYPE_VAR_LEN

Type for sorted bytes DocValues: can have variable lengths

Constructor Detail

SortedBytesDocValuesField

public SortedBytesDocValuesField(String name,
                                 BytesRef bytes)

Create a new variable-length sorted DocValues field.

This calls SortedBytesDocValuesField(name, bytes, false, meaning by default it allows for values of different lengths. If your values are all the same length, use that constructor instead.

Parameters:

name - field name

bytes - binary content

Throws:

IllegalArgumentException - if the field name is null

SortedBytesDocValuesField

public SortedBytesDocValuesField(String name,
                                 BytesRef bytes,
                                 boolean isFixedLength)

Create a new fixed or variable length sorted DocValues field.

Parameters:

name - field name

bytes - binary content

isFixedLength - true if all values have the same length.

Throws:

IllegalArgumentException - if the field name is null
