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()

      DocsEnum docs = null; // reuse
      for (AtomicReaderContext ctx : reader.leaves()) {
        Terms terms = ctx.reader().terms(Consts.FULL);
        if (terms != null) {
          termsEnum = terms.iterator(termsEnum);
          if (termsEnum.seekExact(catTerm, true)) {
            // liveDocs=null because the taxonomy has no deletes
            docs = termsEnum.docs(null, docs, 0 /* freqs not required */);
            // if the term was found, we know it has exactly one document.
            doc = docs.nextDoc() + ctx.docBase;
            break;
