Scaling and configuring search

Version:

This topic describes how to scale and configure Content search and xConnect search.

Search frameworks

The Sitecore Experience Platform has two 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.

The following table summarizes the differences between the search frameworks:

	Content Search	xConnect Search
API	Sitecore Content Search API	xConnect Client API
Providers	Solr SolrCloud	Solr SolrCloud
Indexes	sitecore_core_index sitecore_master_index sitecore_web_index sitecore_marketingdefinitions_master sitecore_marketingdefinitions_web sitecore_marketing_asset_index_master sitecore_marketing_asset_index_web sitecore_testing_index sitecore_suggested_test_index sitecore_fxm_master_index sitecore_fxm_web_index social_messages_master social_messages_web	xdb xdb_rebuild
Indexer	indexCrawler (run on the core Sitecore application)	xConnect Search Indexer (run as Windows Service or Web Job)

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.

Note

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.
