sivaganesh updated SOLR-2908:
-----------------------------
Description:
When we pass the terms.limit parameter to the master (which has many shard
cores), it's not getting pushed down to the individual cores. Instead the
default value of -1 is assigned to Terms.limit parameter is assigned in the
underlying shard cores. The issue being the time taken by the Master core to
return the required limit of terms is higher when we are having more number of
underlying shard cores. This affects the performances of the auto suggest
feature.
Can thought we can have a parameter to explicitly override the -1 being set to
Terms.limit in shards core.
We saw the source code(TermsComponent.java) and concluded that the same. Please
help us in pushing the terms.limit parameter to shard cores.
PFB code snippet.
private ShardRequest createShardQuery(SolrParams params) {
ShardRequest sreq = new ShardRequest();
sreq.purpose = ShardRequest.PURPOSE_GET_TERMS;
// base shard request on original parameters
sreq.params = new ModifiableSolrParams(params);
// remove any limits for shards, we want them to return all possible
// responses
// we want this so we can calculate the correct counts
// dont sort by count to avoid that unnecessary overhead on the shards
sreq.params.remove(TermsParams.TERMS_MAXCOUNT);
sreq.params.remove(TermsParams.TERMS_MINCOUNT);
sreq.params.set(TermsParams.TERMS_LIMIT, -1);
sreq.params.set(TermsParams.TERMS_SORT, TermsParams.TERMS_SORT_INDEX);
return sreq;
