Method Detail

andByScore

SortScoreContext andByScore()

Order elements by their relevance score.

The default order is descending, i.e. higher scores come first.

See Also:

SortContext.byScore()

andByIndexOrder

SortOrderTermination andByIndexOrder()

Order elements by their internal index order.

See Also:

SortContext.byIndexOrder()

andByField

SortFieldContext andByField(String fieldName)

Order elements by the value of a specific field.

The default order is ascending.

The sort field type will be determined automatically if possible, and an exception will be thrown if it is not possible. Automatically determining the type is impossible in particular if a custom field bridge is defined on the given field.

Parameters:

fieldName - The name of the index field to sort by

Throws:

SearchException - If the sort field type could not be automatically determined.

See Also:

SortContext.byField(String), The alternative for numeric fields with custom field bridges.

andByField

SortFieldContext andByField(String fieldName,
                            org.apache.lucene.search.SortField.Type sortFieldType)

Order elements by value of a specific field, with the sort field type provided.

The default order is ascending.

Note: using this method is only required when sorting on a field on which a custom field bridge is defined. Otherwise, one may simply use andByField(String).

Parameters:

fieldName - The name of the index field to sort by

sortFieldType - The sort field type

See Also:

andByField(String, org.apache.lucene.search.SortField.Type)

andByDistance

SortDistanceNoFieldContext andByDistance()

Order elements by distance.

The default order is ascending, i.e. shorter distances come first.

The distance is computed between the value of a field carrying coordinates (to be provided in the next context) and reference coordinates.

See Also:

SortContext.byDistance()

andByNative

SortNativeContext andByNative(org.apache.lucene.search.SortField sortField)

Order element using the native backend API for Lucene.

The sort order (ascending/descending) is defined in sortField

Parameters:

sortField - The sort field to be added to the sort list.

See Also:

SortContext.byNative(SortField)

andByNative

SortNativeContext andByNative(String fieldName,
                              String sortFieldNativeDescription)

Order element using the native backend API for Elasticsearch.

Parameters:

fieldName - The name of the index field to sort by

sortFieldNativeDescription - The sort field description, as valid JSON. This may be a simple quoted string (e.g. "'asc'") or a JSON map (e.g. "{'key': 'value'}"). See Elasticsearch's documentation for information about the exact syntax.
