Method Detail

searchable

boolean searchable()

Returns:

true if search predicates are supported on fields of this type. Some sorts may still be unsupported because they don't make sense (e.g. a "within circle" predicate on a string field).

isSearchable

@Deprecated
default boolean isSearchable()

Deprecated. Use searchable() instead.

Returns:

true if search predicates are supported on fields of this type. Some sorts may still be unsupported because they don't make sense (e.g. a "within circle" predicate on a string field).

sortable

boolean sortable()

Returns:

true if sorts are supported on fields of this type. Some sorts may still be unsupported because they don't make sense (e.g. a distance sort aggregation on a string field).

isSortable

@Deprecated
default boolean isSortable()

Deprecated. Use sortable() instead.

Returns:

true if sorts are supported on fields of this type. Some sorts may still be unsupported because they don't make sense (e.g. a distance sort aggregation on a string field).

projectable

boolean projectable()

Returns:

true if projections are supported on fields of this type. Some projections may still be unsupported because they don't make sense (e.g. a distance projection aggregation on a string field).

isProjectable

@Deprecated
default boolean isProjectable()

Deprecated. Use projectable() instead.

Returns:

true if projections are supported on fields of this type. Some projections may still be unsupported because they don't make sense (e.g. a distance projection aggregation on a string field).

aggregable

boolean aggregable()

Returns:

true if aggregations are supported on fields of this type. Some aggregations may still be unsupported because they don't make sense (e.g. a range aggregation on an analyzed string field).

isAggregable

@Deprecated
default boolean isAggregable()

Deprecated. Use aggregable() instead.

Returns:

true if aggregations are supported on fields of this type. Some aggregations may still be unsupported because they don't make sense (e.g. a range aggregation on an analyzed string field).

dslArgumentClass

Class<?> dslArgumentClass()

Returns:

The expected raw Java type of arguments passed to the DSL for this field.

See Also:

ValueConvert.YES, ToDocumentFieldValueConverter

projectedValueClass

Class<?> projectedValueClass()

Returns:

The raw Java type of projected values for this field.

See Also:

ValueConvert.YES, FromDocumentFieldValueConverter

valueClass

Class<?> valueClass()

Returns:

The raw Java type of values for this field. This may not be the expected type for arguments passed to the DSL for this field, nor the type of projected values for this field. See dslArgumentClass()

analyzerName

Optional<String> analyzerName()

Returns:

The name of the analyzer assigned to this type, if any. Only ever set for String fields.

normalizerName

Optional<String> normalizerName()

Returns:

The name of the normalizer assigned to this type, if any. Only ever set for String fields.

searchAnalyzerName

Optional<String> searchAnalyzerName()

Returns:

The name of the search analyzer assigned to this type, if any. Only ever set for String fields. By default, the search analyzer is the same as the analyzer.
