As we know Solr has a few caches, for example – filterCache for filters, queryResultCache for query results caching and of course the documentCache for caching documents for fast retrieval. Today we will focus on the last of the mentioned caches and what can be done to better utilize the cache if you use it.
Today’s entry is dedicated to one type of cache in the Solr – filter cache. I will try to explain what it does, how to configure it and how to use it in an efficient way.
Hereby I would like to start a small series of articles describing the elements of the optimization of Solr instances. At first glance I decided to describe the parameter that specifies the data fetch window size – the query result window size. Hopefully, this article will explain how to use this parameter, how to modify and adapt it to your needs.
