Search and indexing overview

Current version: 9.0

Sitecore Experience Platform (XP) has three search frameworks:

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

  • 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:

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 9.0, the following indexes are no longer managed by Sitecore Content Search:

  • sitecore_list_index - replaced by the xDB Collection index

  • sitecore_analytics_index - replaced by the xDB Collection index

  • social_messages_master

  • social_messages_web

For information about configuring content indexes, see Search and Indexing.


A Lucene provider is available for Content Search. This provider can only be used in an XP/XM Single and it is not recommended or supported in production.
