When setting `"filter_duplicate_text": true` in `significant_text` aggregation, it changes the count only for the `doc_count` and not for the `bg_count`.  
Meaning the score will count documents that the word appear in as documents that the word doesn't appear in.

This is problematic as a word that appears a lot in duplicated texts has a significantly lower score than it should.

What are your thoughts regarding this?

Thanks
