示例1: constructRequest

/**
* {@inheritDoc}
*/
@Override
public ShardRequest[] constructRequest(ResponseBuilder rb) {
ShardRequest sreq = new ShardRequest();
GroupingSpecification groupingSpecification = rb.getGroupingSpec();
if (groupingSpecification.getFields().length == 0) {
return new ShardRequest[0];
}
sreq.purpose = ShardRequest.PURPOSE_GET_TOP_GROUPS;
sreq.params = new ModifiableSolrParams(rb.req.getParams());
// TODO: base on current params or original params?
// don't pass through any shards param
sreq.params.remove(ShardParams.SHARDS);
// set the start (offset) to 0 for each shard request so we can properly merge
// results from the start.
if(rb.shards_start > -1) {
// if the client set shards.start set this explicitly
sreq.params.set(CommonParams.START,rb.shards_start);
} else {

}
// TODO: should we even use the SortSpec? That's obtained from the QParser, and
// perhaps we shouldn't attempt to parse the query at this level?
// Alternate Idea: instead of specifying all these things at the upper level,
// we could just specify that this is a shard request.
if(rb.shards_rows > -1) {
// if the client set shards.rows set this explicity
sreq.params.set(CommonParams.ROWS,rb.shards_rows);
} else {
sreq.params.set(CommonParams.ROWS, rb.getSortSpec().getOffset() + rb.getSortSpec().getCount());
}
// in this first phase, request only the unique key field
// and any fields needed for merging.
sreq.params.set(GroupParams.GROUP_DISTRIBUTED_FIRST, "true");
