matchingVariantFields property
If a variant Product matches the search query, this map indicates which Product fields are matched.
The key is the Product.name, the value is a field mask of the matched Product fields. If matched attributes cannot be determined, this map will be empty. For example, a key "sku1" with field mask "products.color_info" indicates there is a match between "sku1" ColorInfo and the query.
