TFIDF based on Field

[shambhusingh <sh...@gmail.com>]

Hi All,

I have a situation where i want to give more relevency to a token from
1 field (say Title) than other column say (Brand).
so is there any way we can manipulate the tfidf value based on the field name.

Thanks in Advance

repeat the title for multiple times is a simple hack you could do
