Legacy feature

This article pertains to the Coveo Hive framework which is now in maintenance mode.

Choose one of Coveo’s more modern, lightweight, and responsive libraries for any future search interface development. See the search interface Implementation guide for more details.

Implements the Coveo JavaScript Search Framework Recommendation component to get a result list related to the one executed in the main search interface.

The main purpose of the Coveo Related Query rendering is to execute a second query, slightly different from the current search interface query, which may take into account, or not, the current search interface filters in its advanced query expression (aq) and the current search interface query expression in its basic query expression (q).

Usage notes

The Coveo Related Query rendering always acts as a full-fledged search interface and requires a dedicated analytics component (see Coveo for Sitecore Analytics).
When bound to a search interface through the Main search interface data source option, the Coveo Related Query rendering inherits the Sitecore Instance Filter configurations set on that search interface. When not bound to a search interface, you can add Sitecore Instance Filter and Query Filter renderings in the Recommendations Components placeholder to apply filtering on your Sitecore instance items.
Coveo for Sitecore 5.0.822.2

The Sitecore Instance Filter rendering is now added automatically with the Coveo Related Query rendering. This adds the new Filter results based on the current Sitecore context database data source option which lets you control whether to add a filter on the current Sitecore context database in the constant query expression (cq). Prior to the October 30, 2020 release, related query recommendations were automatically filtered on the current Sitecore context database.
You can customize the CSS associated with this rendering.

Coveo Hive SXA

Coveo for Sitecore SXA rendering insertion locations aren’t limited by placeholder Allowed Controls. The Coveo Related Query rendering may therefore be inserted throughout the partial design, whether in Coveo for Sitecore or Sitecore placeholders.
