A question about maxlenh and maxlend

[hipoglucido]

I understand that if description has more than maxlend words it will be clipped, so some of the "interesting" information could potentially be lost (same with headlines and maxlenh although headlines are shorter so I guess its not that bad). Is there any reason why you set both of them to 25 instead of, let's say, 25 (h) and 70 (d)?
I understand that it may be due to limited computing resources... it's just that my intuition tells me that it is a high price to pay

After cell [4] you say:

I've started with maxlend=0 (see below) in which the description was ignored.

Why would you want to ignore the description? What is the purpose of feeding just headlines without descriptions?

Thanks @udibr :)
