: I don't get really, I try to boost a field according to another one but I've : a huge weight when I'm using qf boost like : : : /select?qt=dismax&fl=*&q="obama : meeting"&debugQuery=true&qf=title&bf=product(title,stat_views)
bf is a boost function -- you are using a product fucntion to multiply the "title" field by the stat_views" field ... this doesn't make sense to me? i'm assuming the "title" field contains text (the rest of your score explanation confirms this). when you try to do a math function on a string based field it deals with the "ordinal" value -- the higher the string is lexigraphically compared to all other docs ,the higher the ordinal value. i have no idea what's in your stat_views field -- but i can't imagine any way in which multipling it by the ordinal value of your text field would make sense... : 5803675.5 = (MATCH) FunctionQuery(product(ord(title),sint(stat_views))), : product of: : 9.5142968E7 = product(ord(title)=1119329,sint(stat_views)=85) : 1.0 = boost : 0.06099952 = queryNorm : But this is not equilibrate between this boost in qf and bf, how can I do ? when it comes to function query, you're on your own to figure out an appropriate query boost to blanace the scores out -- when you use a product function the scores are going to get huge like this unless you balance it somehow (and that ord(title) is just making this massively worse) -Hoss
