Interface IFieldable

Returns length of byte[] segment that is used as value, if Field is not binary returned value is undefined

Returns offset into byte[] segment that is used as value, if Field is not binary returned value is undefined

Gets or sets the boost factor for hits for this field. This value will be multiplied into the score of all hits on this this field of this document.

The boost is multiplied by Boost of the document containing this field. If a document has multiple fields with the same name, all such values are multiplied together. This product is then used to compute the norm factor for the field. By default, in the method, the boost value is multiplied by the and then rounded by EncodeNorm(Single) before it is stored in the index. One should attempt to ensure that this product does not overflow the range of that encoding.

The default value is 1.0.

Note: this value is not stored directly with the document in the index. Documents returned from Document(Int32) and Doc(Int32) may thus not have the same value present as when this field was indexed.

True if the value of the field is stored as binary

True if the value of the field is to be indexed, so that it may be searched on.

Indicates whether a Field is Lazy or not. The semantics of Lazy loading are such that if a Field is lazily loaded, retrieving it's values via StringValue or GetBinaryValue() is only valid as long as the IndexReader that retrieved the Document is still open.

True if the value of the field is to be stored in the index for return with search hits.

True if terms are stored as term vector together with their offsets (start and end positon in source text).

True if terms are stored as term vector together with their token positions.

True if the term or terms used to index this field are stored as a term vector, available from GetTermFreqVector(Int32, String). These methods do not provide access to the original content of the field, only to terms used to index it. If the original content must be preserved, use the stored attribute instead.

True if the value of the field should be tokenized as text prior to indexing. Un-tokenized fields are indexed as a single word and may not be Reader-valued.

Returns the name of the field as an interned string. For example "date", "title", "body", ...

True if norms are omitted for this indexed field.

Expert: If set, omit normalization factors associated with this indexed field. This effectively disables indexing boosts and length normalization for this field.

The value of the field as a Reader, which can be used at index time to generate indexed tokens.

The value of the field as a String, or null.

For indexing, if isStored()==true, the stringValue() will be used as the stored field value unless isBinary()==true, in which case GetBinaryValue() will be used.

If isIndexed()==true and isTokenized()==false, this String value will be indexed as a single token. If isIndexed()==true and isTokenized()==true, then tokenStreamValue() will be used to generate indexed tokens if not null, else readerValue() will be used to generate indexed tokens if not null, else stringValue() will be used to generate tokens.

The TokenStream for this field to be used when indexing, or null.

Return the raw byte[] for the binary field. Note that you must also call BinaryLength and BinaryOffset to know which range of bytes in this returned array belong to the field.

Return the raw byte[] for the binary field. Note that you must also call BinaryLength and BinaryOffset to know which range of bytes in this returned array belong to the field.

About reuse: if you pass in the result byte[] and it is used, likely the underlying implementation will hold onto this byte[] and return it in future calls to GetBinaryValue() or GetBinaryValue(). So if you subsequently re-use the same byte[] elsewhere it will alter this Fieldable's value.
