Description

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); }

}
