Hi, @mosico 

We would usually use type "D" for ambiguous queries such as this https://duckduckgo.com/?q=javascript+indexof or this https://duckduckgo.com/?q=apple (sorry, we're still working on the documentation). Also, for future reference, titles with type "D" should have its content in the disambiguation column (line 27 in your program) instead of the abstract/description column.
