Search finds products by their categories
Your store search can now find a product by the names of the categories it is in. Tick Category names under Products in Store > Settings > Search. A multivitamin filed under Immunity, Energy and Heart Health then shows up for each of those searches, without packing every topic into its title. Products with the word in their own title still come first.
Search also treats punctuation as a gap between words again, so comma-separated meta keywords and category names like "Digestion: Liver" match properly.
