With the release of Solr 7.0 and introduction of new replica types, in addition to the defa?ult NRT type the question appeared – can we control the queries and where they are executed?

Read moreSolrCloud – write and read tolerance
SolrCloud similar to most of the distributed systems is designed with some rules in mind. There are also rules that each distributed system is subject to. For example the CAP theorem tells that a system can’t achieve availability, data consistency and network partition split tolerance at the same time – you can have two out of three at most.

It works on the basis of Solr index and is able to check documents sent to a new handler and return occurrences of names with offsets and other metadata that we added to Solr index.
