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

org.apache.lucene.index.TermsEnum.seekExact()
Attempts to seek to the exact term, returning true if the term is found. If this returns false, the enum is unpositioned. For some codecs, seekExact may be substantially faster than {@link #seekCeil}.
