Interface ProjectionConstants

All Known Subinterfaces:

HSQuery

@Deprecated
public interface ProjectionConstants

Deprecated.

Instead of using Hibernate Search 5 APIs, get a org.hibernate.search.mapper.orm.session.SearchSession using org.hibernate.search.mapper.orm.Search#session(org.hibernate.Session), create a SearchQuery with org.hibernate.search.mapper.orm.session.SearchSession#search(Class), and define your projections using SearchQuerySelectStep.select(Function). Refer to the migration guide for more information.

Defined projection constants.

Implementator's note: When adding new constants, be sure to add them to LuceneHSQuery#SUPPORTED_PROJECTION_CONSTANTS, too.

Field Details

THIS

@Deprecated
static final String THIS

Deprecated.

See the javadoc of this class for how to create projections in Hibernate Search 6. The equivalent projection in Hibernate Search 6 is SearchProjectionFactory.entity().

Represents the Hibernate entity returned in a search.

See Also:

• Constant Field Values

DOCUMENT

@Deprecated
static final String DOCUMENT

Deprecated.

See the javadoc of this class for how to create projections in Hibernate Search 6. The equivalent projection in Hibernate Search 6 is LuceneSearchProjectionFactory.document(). You will need to pass LuceneExtension.get() to SearchProjectionFactory.extension(SearchProjectionFactoryExtension) in order to get access to this Lucene-specific feature.

The Lucene document returned by a search.

See Also:

• Constant Field Values

SCORE

@Deprecated
static final String SCORE

Deprecated.

See the javadoc of this class for how to create projections in Hibernate Search 6. The equivalent projection in Hibernate Search 6 is SearchProjectionFactory.score().

The legacy document's score from a search.

See Also:

• Constant Field Values

ID

@Deprecated
static final String ID

Deprecated.

See the javadoc of this class for how to create projections in Hibernate Search 6. The equivalent projection in Hibernate Search 6 is SearchProjectionFactory.entityReference(); call .id() on the reference to get the entity identifier.

Object id property

• Constant Field Values

EXPLANATION

@Deprecated
static final String EXPLANATION

Deprecated.

See the javadoc of this class for how to create projections in Hibernate Search 6. The equivalent projection in Hibernate Search 6 is LuceneSearchProjectionFactory.explanation(). You will need to pass LuceneExtension.get() to SearchProjectionFactory.extension(SearchProjectionFactoryExtension) in order to get access to this Lucene-specific feature.

Lucene Explanation object describing the score computation for the matching object/document This feature is relatively expensive, do not use unless you return a limited amount of objects (using pagination) To retrieve explanation of a single result, consider retrieving the entity id and using fullTextQuery.explain(Object)

See Also:

• Constant Field Values

OBJECT_CLASS

@Deprecated
static final String OBJECT_CLASS

Deprecated.

See the javadoc of this class for how to create projections in Hibernate Search 6. The equivalent projection in Hibernate Search 6 is SearchProjectionFactory.entityReference(); call .type() on the reference to get the entity type.

Represents the Hibernate entity class returned in a search. In contrast to the other constants this constant represents an actual field value of the underlying Lucene document and hence can directly be used in queries.

See Also:

• Constant Field Values

SPATIAL_DISTANCE

@Deprecated
static final String SPATIAL_DISTANCE

Deprecated.

See the javadoc of this class for how to create projections in Hibernate Search 6. The equivalent projection in Hibernate Search 6 is SearchProjectionFactory.distance(String, GeoPoint).

Represents the distance (in kilometers) between an entity and the center of the search area in case of a spatial query.

• Constant Field Values
