How do I force rank a specific set of products?

You can specify exactly which products you want to show up in the start of your results by using either the Area or Query controls of bringToTop.

Query

You can use the bringToTop query level control to specify a list of product IDs to bring to the top of the result set. You can specify up to 100 IDs. This list will ensure that the products are included in the result set and appear in the order defined. The reserved id field should be used to specify which record is pushed to top.

JSON Reference:

{
   "biasing":{
      "bringToTop":[
         "productId1",
         "productId3",
         "productId2"
      ]
   }
}

Rule

At rule level you can add multiple products to be forced to the top of the returning query, by adding them via the Push To Top screen. This is the same as the bringToTop functionality, just controllable via Command Center.

1. Enter the exact product ID into the textbox field
2. Click “add product ID”
3. Once the product has been added, you can add another product to the list by its ID.

The id you enter into the textbox must be an exact match to the product id field.

You can only add one product ID at a time via the text box, but you can add as many products as you wish to the list, up to 100. Once you have added all the records you’d like to see returned at the top, you can drag and drop them to the order that you want to have them in.

The results will have the products you specified at the top, with the rest of the products obeying the Biasing Profile specified within the rule (or the Area level profile if none was specified).
