how to achive Query with terms' weight to a Boolean matching?
i think my question is unclear/misleading... example
I have a document reads:
"I am eating an apple while using apple computer"
My xapian query:
instead of getting a weight of 11 of this doc (2Xapple 1Xcomputer), how to
make the matching in boolean way so i will get a weight of 7 for this
Is it possible to add "penalty" in a query?
docA = "How to eat an apple while using apple computer"
docB = "I am eating an apple while using apple computer"
Query(apple:4,computer:3,how:-1) << is it possible to penalty / lost weight
when doc has the term "how" so the docB ranks heigher?
how heavy will it be if i add a value of "hash(md5 HTML<title> X
websiteDomain)" to each document, and then use this key to collapse
duplicated-title-in-domain using set_collapse_key? is it way too heavy?
Thanks and really appreciated
