Solr Redis Plugin Use Cases and Performance Tests - Sematext
The Solr Redis Plugin is an extension for Solr that provides a query parser that uses data stored in Redis. It is open-sourced on Github by Sematext. This tool is basically a QParserPlugin that establishes a connection to Redis and takes data stored in SET, ZRANGE and other Redis data structures in order to build a query.

Elasticsearch Refresh Interval vs Indexing Performance - Sematext
Elasticsearch is near-realtime, in the sense that when you index a document, you need to wait for the next refresh for that document to appear in a search. Refreshing is an expensive operation and that is why by default it’s made at a regular interval, instead of after each indexing operation.

Apache Solr Tutorial: What Is, How It Works & What Is It Used For - Sematext
The ability to search is a key feature of most modern applications. While encompassing huge amounts of data, they need to allow the end-user to find what they're searching for without delay.
