> When the attribute 'onePassDistributedQuery' is 'true',QueryCompoent will not send a ShardRequest to retrive field values, highlight values has been return by shards in createMainQuery together.
> See code below:
> private void handleRegularResponses(ResponseBuilder rb, ShardRequest sreq) {
> if ((sreq.purpose & ShardRequest.PURPOSE_GET_TOP_IDS) != 0) {
> //merge all id and score,and ResponseBuilder.resultIds just stored id between start to rows
> mergeIds(rb, sreq);
> }
> if ((sreq.purpose & ShardRequest.PURPOSE_GET_TERM_STATS) != 0) {
> updateStats(rb, sreq);
> }
> if ((sreq.purpose & ShardRequest.PURPOSE_GET_FIELDS) != 0) {
> //where ResponseBuilder.onePassDistributedQuery is true,highlight values was retrived at same time,but not truncated by 'start' and 'rows',just return top N(N=start+rows),
> returnFields(rb, sreq);
> }
> }
