Class SortedDocValuesField

java.lang.Object

org.apache.lucene.document.Field

org.apache.lucene.document.SortedDocValuesField

All Implemented Interfaces:

IndexableField

public class SortedDocValuesField
extends Field

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

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

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

This value can be at most 32766 bytes long.

Constructor Detail

SortedDocValuesField

public SortedDocValuesField(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

newSlowRangeQuery

public static Query newSlowRangeQuery(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 included.

You can have half-open ranges by setting lowerValue = null or upperValue = null.

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[]).

newSlowExactQuery

public static Query newSlowExactQuery(String field,
                                      BytesRef value)

Create a query for matching an exact BytesRef value.

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[]).
