org.apache.lucene.index.TermFreqVector |
Known Indirect Subclasses |
Provides access to stored term vector of
a document field. The vector consists of the name of the field, an array of the terms that occur in the field of the
Document
and a parallel array of frequencies. Thus, getTermFrequencies()[5] corresponds with the
frequency of getTerms()[5], assuming there are at least 5 terms in the Document.

Array of term frequencies. Locations of the array correspond one to one
to the terms in the array obtained from getTerms
method. Each location in the array contains the number of times this

of terms searched for, each slot containing the result of searching for
that term number.
