Parameter not documented

I just saw on
https://github.com/BurritoZz/Haystack/blob/4d35fd50ef8f6b15c5490e4ab6dd523a3c21dca3/searchresult.py#L17
that this parameter lacks documentation.
In this case, the good name makes that I can guess what is does!

What tool do you use to check for completeness of e.g. documentation?
