Scaling and configuring search

Current version: 10.1

When you configure servers, you must select and configure a search and indexing provider. You can select Solr or Azure, depending on your business purpose and the type of server architecture you want to implement.


Search frameworks

The Sitecore Experience Platform has three search frameworks:

  • Content Search, which is used by various components primarily to search and index Sitecore items.

    Sitecore provides you with several options for configuring search results and indexing for content search.

  • xConnect Search, which is used to search and index experience data.

  • Commerce Search, which is used to search and index customers and orders.

The following table summarizes the differences between the three search frameworks:

Commerce Minions

Many components that use the Content Search have their own API layer on top of the Content Search API. For example, the Marketing Operations API has a method for searching the sitecore_marketing_* and sitecore_marketingdefinitions_* indexes that references the Content Search API further down the stack.


In Sitecore 9.0 and later, Sitecore Content Search no longer manages sitecore_list_index and sitecore_analytics_index . The xDB collection index replaces both of these indexes.
