Xapian discuss - Dec 2008 - Does match weight include doc weight from index-time?

Greets,

Does a match weight calculation (BM25) factor in the document page  
weight (eg, $analyzer->index_text( $text, $weight )) used during  
index-time, or is it not related at all?

Thanks
Henry

Found the answer:

parameter k1==importance of wdf ($weight above is wdf increment)
