Consider the following information:• A merchant has this three-tier category structure setup in the Storefront...

The likely reason the merchandiser does not see the Search Refinement when searching for "Clothing" via the Storefront search, despite it being configured for the Clothing category, is option B: "The Search Refinement definition is not set up for the Women category." Search Refinements need to be set up at each level of the category hierarchy to be effective in searches that aggregate products across those categories. If the refinement is only set for "Clothing" but not for "Women," it won't appear in searches that include items from the broader "Women" category or that are initiated from a higher category level.
