DocValueType

DocValues DocValuesType: if not NONE then the field's value will be indexed into docValues.

Declaration

Property Value
Type Description
DocValuesType

IndexOptions

IndexOptions, describing what should be recorded into the inverted index

Declaration

IsIndexed

true if this field should be indexed (inverted)

Declaration
bool IsIndexed { get; }
Property Value
Type Description
System.Boolean

IsStored

true if the field's value should be stored

Declaration
bool IsStored { get; }
Property Value
Type Description
System.Boolean

IsTokenized

true if this field's value should be analyzed by the Analyzer.

This has no effect if IsIndexed returns false.

Declaration
bool IsTokenized { get; }
Property Value
Type Description
System.Boolean

OmitNorms

true if normalization values should be omitted for the field.

This saves memory, but at the expense of scoring quality (length normalization will be disabled), and if you omit norms, you cannot use index-time boosts.

Declaration
bool OmitNorms { get; }
Property Value
Type Description
System.Boolean

StoreTermVectorOffsets

true if this field's token character offsets should also be stored into term vectors.

This option is illegal if term vectors are not enabled for the field (StoreTermVectors is false)

Declaration
bool StoreTermVectorOffsets { get; }
Property Value
Type Description
System.Boolean

StoreTermVectorPayloads

true if this field's token payloads should also be stored into the term vectors.

This option is illegal if term vector positions are not enabled for the field (StoreTermVectors is false).

Declaration
bool StoreTermVectorPayloads { get; }
Property Value
Type Description
System.Boolean

StoreTermVectorPositions

true if this field's token positions should also be stored into the term vectors.

This option is illegal if term vectors are not enabled for the field (StoreTermVectors is false).

Declaration
bool StoreTermVectorPositions { get; }
Property Value
Type Description
System.Boolean

StoreTermVectors

true if this field's indexed form should be also stored into term vectors.

this builds a miniature inverted-index for this field which can be accessed in a document-oriented way from GetTermVector(Int32, String).

This option is illegal if IsIndexed returns false.

Declaration
bool StoreTermVectors { get; }
Property Value
Type Description
System.Boolean
