The AbstractField type exposes the following members.
Constructors
Name | Description | |
---|---|---|
AbstractField()()()() | Initializes a new instance of the AbstractField class | |
AbstractField(String, Field..::..Store, Field..::..Index, Field..::..TermVector) | Initializes a new instance of the AbstractField class |
Methods
Name | Description | |
---|---|---|
BinaryValue | ||
Equals | (Inherited from Object.) | |
Finalize | Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) | |
GetBinaryLength | Returns length of byte[] segment that is used as value, if Field is not binary
returned value is undefined
| |
GetBinaryOffset | Returns offset into byte[] segment that is used as value, if Field is not binary
returned value is undefined
| |
GetBinaryValue()()()() | Return the raw byte[] for the binary field. Note that
you must also call {@link #getBinaryLength} and {@link
#getBinaryOffset} to know which range of bytes in this
returned array belong to the field.
| |
GetBinaryValue(array<Byte>[]()[][]) | ||
GetBoost | Returns 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 {@link Lucene.Net.Index.IndexReader#Document(int)} and
{@link Lucene.Net.Search.Hits#Doc(int)} may thus not have the same value present as when
this field was indexed.
| |
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) | |
GetOmitNorms | True if norms are omitted for this indexed field | |
GetOmitTermFreqAndPositions | ||
GetOmitTf | Obsolete. | |
GetType | Gets the Type of the current instance. (Inherited from Object.) | |
IsBinary | True iff the value of the filed is stored as binary | |
IsCompressed | True if the value of the field is stored and compressed within the index | |
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 {@link Lucene.Net.Index.IndexReader#GetTermFreqVector(int,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 CopyC# stored | |
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.
| |
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) | |
Name | Returns the name of the field as an interned string.
For example "date", "title", "body", ...
| |
ReaderValue | ||
SetBoost | Sets the boost factor hits on 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 {@link Lucene.Net.Documents.Document#GetBoost()} 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 {@link
Lucene.Net.Search.Similarity#ComputeNorm(String,
FieldInvertState)} method, the boost value is multipled
by the {@link
Lucene.Net.Search.Similarity#LengthNorm(String,
int)} and then
rounded by {@link Lucene.Net.Search.Similarity#EncodeNorm(float)} before it is stored in the
index. One should attempt to ensure that this product does not overflow
the range of that encoding.
| |
SetOmitNorms | Expert:
If set, omit normalization factors associated with this indexed field.
This effectively disables indexing boosts and length normalization for this field.
| |
SetOmitTermFreqAndPositions | 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 {@link
PhraseQuery} or {@link SpanQuery} subclasses will
silently fail to find results.
| |
SetOmitTf | Obsolete. | |
SetStoreTermVector | ||
StringValue | ||
TokenStreamValue | ||
ToString | Prints a Field for human consumption. (Overrides Object..::..ToString()()()().) |
