Pages that display facets typically include refinement counts, which show the number of items in each selection. For example, the selection values displayed for a color facet might look like this:
The values in parentheses are the refinement counts. If the user clicks on the Black selection value, for example, 2 items will be displayed.
Note that these refinement counts may not match the number of search results. For example, in this figure, the number of search results is 3, but if you add up the refinement counts, you get 5. This is because some search results appear in multiple facet selections, because the index is based on products but SKU properties are used for faceting. In this example, one of the products is available in Black, Grey, and Khaki, so it is included in the counts for all three of those colors.
There are various other situations where refinement counts won’t match the number of search results. For example, if you use SKU-based indexing but group results by product, the refinement counts will reflect the number of SKUs returned, but the result count will be the number of products.
