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.

Coveo for Sitecore Specific Rendering Implements the CoveoForSitecoreRankingExpression component which represents a query ranking expression (QRE) created from rules defined in the Sitecore Rules Editor. This query ranking expression is added to the advanced query expression (aq) on calls to the Search API to modify the item ranking score value.

Usage notes

  • The Sitecore Rules Editor is only available with the Enterprise Edition. The Sitecore Rules Editor is required to set Boost expression rules in the data source.

  • The Query Ranking rendering is added automatically with the Coveo Search Interface rendering and Coveo Tab renderings.

  • You need to insert the Coveo Relevancy Sort rendering and select this sorting criterion for your result list to obtain document score values, otherwise score values will be zero on all result items.

  • Boosting is cumulative. When you specify boosting rules on the Coveo Search Interface and on the active Coveo Tab, items matching both rules are boosted by the sum of both modifier numbers.

Sample Generated HTML and Corresponding Result

To boost the score of commerce items currently on sale by 1000 points, you define the following query ranking rule with a number value of 100 (as per the modifier-score 1 to 10 ratio) in the Coveo Search Interface data source:
