Yes, this has been available for a few years now. Initially, they only indexed a very small number of shops, so it was less useful. Based on a few queries, it seems like the are still using some form of text-based search with rank boosting. Seems like they still aren't searching their entire base of shops, but they have increased the number of shops for sure, and they seem to be continuing to invest in the product, which is nice. It seems more useful now than it did the last time I checked!
