Method Detail

asc

public SortFieldContext asc()

Description copied from interface: SortOrder

Sort in ascending order.

Specified by:

asc in interface SortOrder<SortFieldContext>

desc

public SortFieldContext desc()

Description copied from interface: SortOrder

Sort in descending order.

Specified by:

desc in interface SortOrder<SortFieldContext>

createSort

public org.apache.lucene.search.Sort createSort()

Description copied from interface: SortTermination

Return the Lucene Sort corresponding to the requested sort.

Specified by:

createSort in interface SortTermination

onMissingValue

public SortMissingValueContext<SortFieldContext> onMissingValue()

Description copied from interface: SortFieldContext

Describe how to treat missing values when doing the sorting.

Specified by:

onMissingValue in interface SortFieldContext

sortLast

public SortFieldContext sortLast()

Description copied from interface: SortMissingValueContext

Put documents with missing values last in the sorting.

This instruction is independent of whether the sort is being ascending or descending.

Specified by:

sortLast in interface SortMissingValueContext<SortFieldContext>

sortFirst

public SortFieldContext sortFirst()

Description copied from interface: SortMissingValueContext

Put documents with missing values first in the sorting.

This instruction is independent of whether the sort is being ascending or descending.

Specified by:

sortFirst in interface SortMissingValueContext<SortFieldContext>

use

public SortFieldContext use(Object value)

Description copied from interface: SortMissingValueContext

When documents are missing a value on the sort field, use the given value instead.

Lucene sort API limits this feature to numeric fields. As Hibernate Search sorts are currently based on the Lucene API underneath, this is only available for numeric fields for all the indexing services, Elasticsearch included.

Field bridges, if any, will be ignored. Thus the actual numeric value must be provided.

Specified by:

use in interface SortMissingValueContext<SortFieldContext>
