Examples of org.apache.lucene.index.TermsEnum.docsAndPositions()

org.apache.lucene.index.TermsEnum.docsAndPositions()
Get {@link DocsAndPositionsEnum} for the current term.Do not call this when the enum is unpositioned. This method will return null if positions were not indexed. @param liveDocs unset bits are documents that should notbe returned @param reuse pass a prior DocsAndPositionsEnum for possible reuse @see #docsAndPositions(Bits,DocsAndPositionsEnum,int)
