Exclude rules for slots
Exclude rules for slots
In the Recommendations manager of the Coveo Merchandising Hub (CMH), merchandisers can define exclude filter rules to hide specific products from being displayed in recommendation slots.

Use case examples
Exclude filter rules can be used to address a variety of use cases. Here are a few examples:
-
You want to ensure that out-of-stock products aren’t displayed in recommendation slots. For example, you can create a rule to exclude products where the
ec_in_stock
attribute value isfalse
. -
You want to ensure that products with certain undesirable attributes aren’t shown in a recommendation slot. For example, you can create a rule to exclude products where the
ec_category
attribute value isPadlocks
.
Prerequisites
To create rules in the Coveo Merchandising Hub (CMH), you must meet the following prerequisites:
-
In the Coveo Administration Console, the metadata that you want to use as attributes in rules has been mapped to the corresponding fields. These fields must have the Facet or Multi-value facet option enabled. For example, to use the
color
metadata as an attribute in a rule, it must be mapped to a field with the Facet or Multi-value facet option enabled. -
You must choose the correct property to ensure that your changes affect the intended slots.

-
From the navigation tabs, select filter rules and then click Create filter rule.

Under Value, select one or more attribute values that you want to use to filter products. For example, to exclude products based on the
ec_brand
attribute, enter the brand value that you want to use as a filter, such as Barca Sports.For a recommendation slot using a seeded strategy, you can select the Use "Same as product…" option to use a dynamic value. For example, on a PDP, you can create an exclude rule that uses the
ec_brand
attribute and the Use "Same as product…" option to exclude products from the same brand as the product being viewed. When a visitor views aBarca Sports
product, the recommendation slot will exclude otherBarca Sports
products. -
