hmm a idea would be to create dynamically a boost table (field,
boostvalue) in a extended version of a TermQuery depending on the
field:
ex: StructuredTermQuery ("search2", "coco")
1-> Update a boost table according to:
* the virtual structure :
> -structured index
> search1
> search2
> search4
> search3
> search5
* the fact the score is decrease with the dept :
* the search field argument, here "search2"
So for this exemple the table would be = (search1_boost=0,
search2_boost=1, search3_boost=0, search4_boost=0.7)
2- According to the table , a new Query is created with just non zero
boost search field search2:coco^search1_boost
search4:coco^search2_boost
WDYT ?
other proposals more flexible, clever, faster ?
