Search index descriptions

Version: 10.0

When you set up Sitecore servers for scalability, you must also configure a search and indexing provider. In Solr, search indexes are referred to as cores.

The following table describes the default search indexes available in Sitecore:

Index name	Refers to
`sitecore_core_index`	The Core database and the items that define the Sitecore CMS interfaces.
`sitecore_master_index`	The Master database that contains all versions of every item, including unpublished versions. This is everything related to the published website.
`sitecore_web_index`	The Web database that contains only the published versions of every item in all languages.
`sitecore_marketingdefinitions_master`	The marketing definition data that is stored in the master database. It is only used on the content management environment and is not shared.
`sitecore_marketingdefinitions_web`	The marketing definition data that is stored in the Web database. It is only used on the content delivery environment and is not shared.
`sitecore_marketing_asset_index_master`	The marketing asset data that is stored in the Master database. It is only used on the content management environment and is not shared. Use the marketing operations API to query marketing assets.
`sitecore_marketing_asset_index_web`	The marketing asset data that is stored in the Web database. It is only used on the content delivery environment and is not shared. Use the marketing operations API to query marketing assets.
`sitecore_personalization_index`	The personalization index stores information about which page definition items in the content tree are personalized and which personalization rules the pages use. The index is used in Experience Optimization by the Personalization dashboard.
`sitecore_testing_index`	The test definition items used in the test lists in Experience Optimization and the Experience Editor. This does not include the suggested tests list. It is also used in the Sitecore client UI to report on any tests present on an item.
`sitecore_suggested_test_index`	Provides storage for computed values for all of the content items in the content tree, and is used to suggest the items that should be optimized. This index drives the suggested test list in the Experience Optimization and inside the Experience Editor. It is also used in the Sitecore client UI to show when a test has ended.
`sitecore_fxm_master_index`	All versions of every item on your FXM websites. Changes that you make to the content are added every time the index is rebuilt. It is only used in the content management environment and is not shared.
`sitecore_fxm_web_index`	The published versions of every item on your FXM websites. Changes that you make to the content are added every time the index is rebuilt.
