Fields
Properties
| Name | Description |
|---|---|
| BinaryLength | Returns length of byte[] segment that is used as value, if Field is not binary returned value is undefined |
| BinaryOffset | Returns offset into byte[] segment that is used as value, if Field is not binary returned value is undefined |
| Boost | Gets or sets the boost factor for hits for this field. 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. |
| IsBinary | True iff the value of the filed is stored as binary |
| IsIndexed | True iff the value of the field is to be indexed, so that it may be searched on. |
| IsLazy | |
| IsStored | True iff the value of the field is to be stored in the index for return with search hits. It is an error for this to be true if a field is Reader-valued. |
| IsStoreOffsetWithTermVector | True iff terms are stored as term vector together with their offsets (start and end position in source text). |
| IsStorePositionWithTermVector | True iff terms are stored as term vector together with their token positions. |
| IsTermVectorStored | True iff 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 |
| IsTokenized | True iff 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. |
| Name | Returns the name of the field as an interned string. For example "date", "title", "body", ... |
| OmitNorms | True if norms are omitted for this indexed field |
| OmitTermFreqAndPositions | Expert: If set, omit term freq, positions and payloads from postings for this field. NOTE: While this option reduces storage space required in the index, it also means any query requiring positional information, such as PhraseQuery or Lucene.Net.Search.Spans.SpanQuery subclasses will silently fail to find results. |

Methods
| Name | Description |
|---|---|
| GetBinaryValue() | 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. |
| GetBinaryValue(Byte[]) | |
| SetStoreTermVector(Field.TermVector) | |
| ToString() | Prints a Field for human consumption. |
