List of seekExact() Examples

Examples of 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}.

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

    Terms terms = indexReader.terms(field);
    if (terms == null) {
      return null;
    }
    TermsEnum iterator = terms.iterator(null);
    if (iterator.seekExact(term)) {
      return iterator.docs(bits, null, random().nextBoolean() ? DocsEnum.FLAG_FREQS : DocsEnum.FLAG_NONE);
    }
    return null;
  }
