It's decent, but most often DuckDuckGo gives more relevant stack overflow answers than stack overflow itself does for the same query. Even though SO has far more information to tune the results on than DDG.
Another "proof" of how bad their search is, can be witnessed in the millions of duplicates. SO basically got an army of volunteers who know how to operate this search within their niche, to close duplicates, something that a decent search result would solve for a big part.
