Ranking adjustments are a powerful way to fine-tune search results using your business data and a variety of different boosts options. These boosts provide the building blocks for promotions, merchand
Boosts can only be applied to indexed fields.
Filter boosts are a great way to promote and personalize results. Combined with conditions, they provide a powerful tool to adjust the ranking of your search results to optimize your business metrics.
Assuming you want to run a promotion on Nike products in your online store. The following Filter boost will boost Nike products by a score of 0.8.
But filter boosts aren't limited to pre-defined values like "nike" in the example above. The filter expression can reference dynamic parameters passed into the search.
To personalize results, you can pass information about the user, such as brand affinity, into the search query and improve the search results based on that data.
In the above query example, we are passing a variable called "brandAffinity" to the search query. The variable can be referenced in the filter boost like so:
Boost results that fall within a specific numeric range. Boosting is applied linearly between the start and the end point. Use range boosts to boost highly rated products, popular products or inventory that needs to be sold.
Assume that you have a rating field that ranges between 0-5 and the values can be decimal values (not just whole numbers). You want to boost values between 2-4 in a linear manner, where 2 receives the smallest boost and 4 (and above) the maximum boost. Ratings between 0 and 2 will receive no boost.
The configuration for this would look as follows, where the score boost of 0.4 is the maximum boost applied to values of 4 and above.
