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

org.apache.lucene.index.TermsEnum.docs()
Get {@link DocsEnum} for the current term. Do notcall this when the enum is unpositioned. This method will not return null. @param liveDocs unset bits are documents that should notbe returned @param reuse pass a prior DocsEnum for possible reuse
