Envato search engine?

If envato is making so much money and is so successful why can they not afford to set up a real search engine… it’s no better now than it was 5 years ago… it’s hard to believe that proper indexes with more than two or three keywords cannot be setup for a site where searching is a fundamental function for buyers… I can imagine it must be frustrating for authors/sellers also when searches for their product result in 0 results… I see many other threads about this but never any answer from envato… the technology is available.
