SolrQuery::setGroupCachePercent

Description

Setting this parameter to a number greater than 0 enables caching for result grouping. Result Grouping executes two searches; this option caches the second search. The server default value is 0.

For simple queries like term or "match all" queries, group caching degrades performance. group.cache.percent parameter
