Even if a hyphen was used rather than an em or en dash, the dictionary should still attempt to look up the word(s) and give you options to choose from. How difficult would it be to look up the word up to the hyphen/dash? Not difficult at all. They could easily fix this by offering us the option to look up the word up to the hyphen/dash and any hyphenated words based on that one. But as usual, Amazon never listens to us so they probably don't know this issue exists.
