Class LucenePropertyIndex

java.lang.Object

org.apache.jackrabbit.oak.plugins.index.search.spi.query.FulltextIndex

org.apache.jackrabbit.oak.plugins.index.lucene.LucenePropertyIndex

All Implemented Interfaces:

QueryIndex, QueryIndex.AdvancedQueryIndex, QueryIndex.AdvanceFulltextQueryIndex, QueryIndex.FulltextQueryIndex, QueryIndex.NativeQueryIndex

public class LucenePropertyIndex
extends org.apache.jackrabbit.oak.plugins.index.search.spi.query.FulltextIndex

Used to query new (compatVersion 2) Lucene indexes. Provides a QueryIndex that does lookups against a Lucene-based index

To define a lucene index on a subtree you have to add an oak:index node. Under it follows the index definition node that:

• must be of type oak:QueryIndexDefinition
• must have the type property set to lucene
• must have the async property set to async

Optionally you can add

• what subset of property types to be included in the index via the includePropertyTypes property
• a blacklist of property names: what property to be excluded from the index via the excludePropertyNames property
• the reindex flag which when set to true, triggers a full content re-index.

 {
     NodeBuilder index = root.child("oak:index");
     index.child("lucene")
         .setProperty("jcr:primaryType", "oak:QueryIndexDefinition", Type.NAME)
         .setProperty("type", "lucene")
         .setProperty("async", "async")
         .setProperty("reindex", "true");
 }

Method Detail

getMinimumCost

public double getMinimumCost()

Description copied from interface: QueryIndex

Returns the minimum cost which QueryIndex.getCost(Filter, NodeState) would return in the best possible case.

The implementation should return a static/cached value because it is called very often.

Returns:

the minimum cost for the index

getIndexName

public String getIndexName()

Description copied from interface: QueryIndex

Get the generic index name (normally the index type).

Returns:

the index name

query

public Cursor query(QueryIndex.IndexPlan plan,
                    NodeState rootState)

Description copied from interface: QueryIndex.AdvancedQueryIndex

Start a query. The filter and sort order of the index plan is to be used.

The index plan is one of the plans that the index returned in the getPlans call.

Parameters:

plan - the index plan to use

rootState - root state of the current repository snapshot

Returns:

a cursor to iterate over the result

performAdditionalWraps

@NotNull
public static @NotNull org.apache.jackrabbit.oak.plugins.index.lucene.LuceneRequestFacade<Query> performAdditionalWraps(@NotNull
                                                                                                                                 @NotNull List<Query> qs)

Perform additional wraps on the list of queries to allow, for example, the NOT CONTAINS to play properly when sent to lucene.

Parameters:

qs - the list of queries. Cannot be null.

Returns:

the request facade
