Class SortedSetDocValuesField

java.lang.Object

org.apache.lucene.document.Field

org.apache.lucene.document.SortedSetDocValuesField

All Implemented Interfaces:

IndexableField

public class SortedSetDocValuesField
extends Field

Field that stores a set of per-document BytesRef values, indexed for faceting,grouping,joining. Here's an example usage:

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

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

Each value can be at most 32766 bytes long.

Constructor Details

SortedSetDocValuesField

public SortedSetDocValuesField(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 Details

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.

This query also works with fields that have indexed SortedDocValuesFields.

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.

This query also works with fields that have indexed SortedDocValuesFields.

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[]).
