Examples of org.apache.lucene.index.TermPositionVector

org.apache.lucene.index.TermPositionVector
Extends TermFreqVector to provide additional information about positions in which each of the terms is found. A TermPositionVector not necessarily contains both positions and offsets, but at least one of these arrays exists.
