(

SearchEngine

$engine

)

A list of search engine hints for this field.

Hints are usually specific to a search engine implementation and allow to fine control how the search engine will handle this particular field.

For example some search engine permits some optimizations at index time by ignoring an update if the updated value does not change by more than X% on a numeric value.

getMapping()

SearchIndexField::getMapping

(

SearchEngine

$engine

)

Get mapping for specific search engine.

Parameters

SearchEngine

$engine

Returns

array|null Null means this field does not map to anything

Implemented in SearchIndexFieldDefinition, DummySearchIndexFieldDefinition, and NullIndexField.

merge()

SearchIndexField::merge

(

SearchIndexField

$that

)

Merge two field definitions if possible.

Parameters

SearchIndexField

$that

Returns

SearchIndexField|false New definition or false if not mergeable.

Implemented in SearchIndexFieldDefinition, and NullIndexField.

setFlag()

SearchIndexField::setFlag	(		$flag,
			$unset = false
