What steps should be taken to refine product search results by a custom attribute called weightCapacity?

Refining product search results by a custom attribute such as weightCapacity involves ensuring that the search functionality can effectively utilize that attribute to filter and display products. Defining a search refinement for weightCapacity allows customers to filter their search results based on this specific attribute, making it easier for them to find products that meet their needs.

By setting up a search refinement, you enable the system to recognize weightCapacity as a criterion for filtering results. This is crucial because customers may have distinct preferences or requirements based on this attribute, and providing them with the option to refine their search enhances the overall user experience.

Rebuilding the product search index after defining this refinement ensures that all product catalog data is updated to include the new refinement capability. When the index is rebuilt, the search algorithm takes into account the new criteria, allowing for accurate and relevant search results based on the weightCapacity attribute.

In summary, by defining a search refinement for weightCapacity, you allow users to easily narrow their searches based on this custom attribute, and rebuilding the product search index ensures that this feature is fully integrated and functional in the search experience.
