Elasticsearch
Litium uses Elasticsearch as the search engine for searching on the Accelerator site. This article explains the general concepts and things to watch out for.
Elasticsearch is a third-party product that is specialized in fast distributed searches.
It is used as a centralized search index that is used for multiple web-fronts in a multi-server environment. This allows having the same result for the same search result for a site. The same Elasticsearch cluster can be used for multiple Litium applications.
In Litium 7.4 the ES search index is used to search for content in the Websites and Products areas. The Sales area works with inbuilt Lucene.NET.
