Class it.unimi.dsi.mg4j.index.IndexReader

Examples of it.unimi.dsi.mg4j.index.IndexReader.documents()

it.unimi.dsi.mg4j.index.IndexReader.documents()
Returns a document iterator over the documents containing a term.
Note that the index iterator returned by this method will return null on a call to {@link IndexIterator#term() term()}.
Note that it is always possible to call this method with argument 0, even if the underlying index does not provide random access. @param termNumber the number of a term. @throws UnsupportedOperationException if this index reader is not accessible by termnumber.

    final IndexReader reader0 = index0.getReader(), reader1 = index1.getReader();
    IndexIterator i0, i1;
    for ( int i = 0; i < numTerms; i++ ) {
      if ( terms != null ) {
        final CharSequence term = terms.next();
        i0 = reader0.documents( term );
        i1 = reader1.documents( term );
      }
      else {
        i0 = reader0.documents( i );
        i1 = reader1.documents( i );
