I recently used following search string:
here-word here-string OR here-doc
on DDG as well as on Google. The results can be viewed in a screenshot compilation below

Google shows almost exclusively "relevant" results, whereas DDG tries to resolve the "here-word" portion of my search string. "here-word" is, of course, bollocks. It's my mistake, but Google resolved it anyway. DDG didn't. I tried it in several variants (e.g. quotes instead of hyphens) but the results were roughly the same.
So I was wondering whether a search engine should be able to deal with such lapses? Two out of three parts of my search string were very specific technical terms. They appear as titles on many webpages, whereas "here-word" is a meaningless neologism.
BTW: with Google, the hyphen seems to work as a slightly weaker variant of the quote. How is it meant to work with DDG?
Thanks for your attention
