The search function on our mobile site (using 9.3 with the integrated mobile site) doesn't find SKU's on items with multiple variants. The way I have those set up on the site is with a blank SKU on the parent, then the full unique SKU on each child variant. In the past, I've found that the main site's search works similarly when I have full-text search enabled, so it isn't set up for our site.

Any ideas for getting the mobile search to look for variant SKUs? We use SKUs heavily for customer service purposes, so this would help tremendously.
