Examples of it.unimi.dsi.mg4j.index.IndexIterator.term()

it.unimi.dsi.mg4j.index.IndexIterator.term()
Returns the term whose inverted list is returned by this index iterator.
Usually, the term is automatically set by {@link IndexReader#documents(CharSequence)} or {@link IndexReader#documents(int)}, but you can supply your own term with {@link #term(CharSequence)}. @return the term over which this iterator is built, as a compact mutable string. @throws IllegalStateException if no term was set when the iterator was created. @see #termNumber()

      result = MultiTermIndexIterator.getInstance( curr.top(), indexIterator ).weight( weights.popDouble() );

    catch ( IOException e ) {
      throw new QueryBuilderVisitorException( e );
    }
    result.term( node.toString() );
    return result;

    if ( indexMap == null ) throw new IllegalArgumentException( "You cannot use Select nodes without an index map" );
