Google does a pretty decent job for me in Dutch; Duckduckgo and Bing are awful to the point of being useless. Don't agree with your hypothesis either, results are bad even for short simple sentences with common non-combined nouns. They aren't that common in Dutch anyway unless they have evolved into a more or less standalone noun. Dutch nor English people really think of a flamethrower as a thrower of flames, it's just another noun.
