Dear author, Is that possible we can enable fastbit to answer the query ( says, 1 < a < 10 AND 2< b < 5 ) only by looking up index? I don't need the exact answer now, only approximate answer will be fine. Currently, I have codes like following: 1. bis::query aquery(ibis::util::userName(), &table);2. aquery.setWhereClause (wc.str().c_str()); 3. aquery.evaluate ();4. vector <uint32_t> RIDs;5. aquery.getHitRows (RIDs); But I found out for some queries, fastbit need to retrieve data from raw data. I verified this by following : 1. remove the raw data under fastbit folder 2. do the query 3. if there is no error, it means fastbit does not touch the data 4. otherwise (fastbit complains missing raw data), it means fastbit touches the raw data is there some APIs which allow me to do that ? thanks nan
