Field Details

USE_LEGACY_SEMANTIC_TEXT_FORMAT

public static final Setting<Boolean> USE_LEGACY_SEMANTIC_TEXT_FORMAT

Internal index setting to control the format used for semantic text fields. Determines whether to use the legacy format (default: true). This setting is immutable and can only be defined at index creation to ensure the internal format remains consistent throughout the index's lifecycle.

NAME

public static final String NAME

• Constant Field Values

CONTENT_TYPE

public static final String CONTENT_TYPE

Constructor Details

InferenceMetadataFieldsMapper

protected InferenceMetadataFieldsMapper(MappedFieldType inferenceFieldType)

Method Details

contentType

protected String contentType()

Specified by:

contentType in class FieldMapper

fieldType

public InferenceMetadataFieldsMapper.InferenceMetadataFieldType fieldType()

Overrides:

fieldType in class FieldMapper

isEnabled

public static boolean isEnabled(Settings settings)

Checks if the InferenceMetadataFieldsMapper is enabled for the given Settings. This indicates whether the new format for semantic text fields is active. The new format is enabled if: 1. The index version is on or after IndexVersions.INFERENCE_METADATA_FIELDS_BACKPORT, and 2. The legacy semantic text format is disabled.

Parameters:

settings - the index settings to evaluate

Returns:

true if the new format is enabled; false otherwise

isEnabled

public static boolean isEnabled(MappingLookup mappingLookup)

Checks if the InferenceMetadataFieldsMapper is enabled based on the provided Mapping. This indicates whether the new format for semantic text fields is active by verifying the existence of the InferenceMetadataFieldsMapper in the mapping's metadata.

Parameters:

mappingLookup - the mapping to evaluate

Returns:

true if the InferenceMetadataFieldsMapper is present; false otherwise
