boolean splitQueriesOnWhitespace,
boolean eagerGlobalOrdinals)

Method Details

typeName

public java.lang.String typeName()

Description copied from class: MappedFieldType

Returns the name of this type, as would be specified in mapping properties

Specified by:

typeName in class MappedFieldType

eagerGlobalOrdinals

public boolean eagerGlobalOrdinals()

Overrides:

eagerGlobalOrdinals in class MappedFieldType

Returns:

if this field type should load global ordinals eagerly

valueForDisplay

public java.lang.Object valueForDisplay(java.lang.Object value)

Description copied from class: MappedFieldType

Given a value that comes from the stored fields API, convert it to the expected type. For instance a date field would store dates as longs and format it back to a string in this method.

Overrides:

valueForDisplay in class MappedFieldType

fielddataBuilder

public IndexFieldData.Builder fielddataBuilder(java.lang.String fullyQualifiedIndexName,
java.util.function.Supplier<SearchLookup> searchLookup)

Description copied from class: MappedFieldType

Return a fielddata builder for this field

Overrides:

fielddataBuilder in class MappedFieldType

Parameters:

fullyQualifiedIndexName - the name of the index this field-data is build for

searchLookup - a SearchLookup supplier to allow for accessing other fields values in the context of runtime fields

valueFetcher

public ValueFetcher valueFetcher(SearchExecutionContext context,
java.lang.String format)

Description copied from class: MappedFieldType

Create a helper class to fetch field values during the FetchFieldsPhase.

New field types must implement this method in order to support the search 'fields' option. Except for metadata fields, field types should not throw UnsupportedOperationException since this could cause a search retrieving multiple fields (like "fields": ["*"]) to fail.

valueFetcher in class MappedFieldType
