@OutputTimeUnit(TimeUnit.MICROSECONDS)
public void readWithPreFilter(Blackhole blackhole) throws Exception {
    Filter filter = new SelectorFilter("dimSequential", "199");
    StorageAdapter sa = new QueryableIndexStorageAdapter(qIndex);
    Sequence<Cursor> cursors = makeCursors(sa, filter);
    Sequence<List<String>> stringListSeq = readCursors(cursors, blackhole);
    List<String> strings = Sequences.toList(Sequences.limit(stringListSeq, 1), Lists.<List<String>>newArrayList()).get(0);
    for (String st : strings) {
        blackhole.consume(st);
    }
}
