List of termPositions() Examples

Examples of termPositions()

org.apache.lucene.index.IndexReader.termPositions()
Returns an enumeration of all the documents which contain term. For each document, in addition to the document number and frequency of the term in that document, a list of all of the ordinal positions of the term in the document is available. Thus, this method implements the mapping:
This positional information facilitates phrase and proximity searching.
The enumeration is ordered by document number. Each document number is greater than all that precede it in the enumeration. @throws IOException if there is a low-level IO error
