Method GetTermFreqVector
GetTermFreqVector(Int32, String)
Return a term frequency vector for the specified document and field. The returned vector contains terms and frequencies for the terms in the specified field of this document, if the field had the storeTermVector flag set. If termvectors had been stored with positions or offsets, a TermPositionVector is returned.
Declaration
public abstract ITermFreqVector GetTermFreqVector(int docNumber, String field)Parameters
| Type | Name | Description |
|---|---|---|
| System.Int32 | docNumber | document for which the term frequency vector is returned |
| String | field | field for which the term frequency vector is returned. |
Returns
| Type | Description |
|---|---|
| ITermFreqVector | term frequency vector May be null if field does not exist in the specified document or term vector was not stored. |
