Hello Teodor,

Why is a word number more meaningful for ranking? Are the first 100
words more important than the rest? That seems as ambiguous as saying
the first 1000 bytes are more important, no?

Or does the ranking work with the word numbers internally to do
something more clever?

Do you understand why I find the word number inconvenient?

Regards

Markus
