Also, would like to understand what are the ways to optimize for performance
at search time with LTR. Queries with terms (that fetch more results) lead
to very high latency with re-rank query even for reRankDocs=24.
Is there best practices to reduce the latency?
Can fv cache help?
<cache name="QUERY_DOC_FV"
class="solr.search.LRUCache"
size="4096"
initialSize="2048"
autowarmCount="4096"
regenerator="solr.search.NoOpRegenerator" />
Should I increase the cache size?
