I believe so, though I would test it out.
You could try it out in http://splainer.io and confirm the scores are
identical

Hi,
I have found in my code few boost functions like this one:
bf=sum(product(max(field_a,1),10),product(max(field_b,1),100))
The question is, may I split this in two:
bf=product(max(field_a,1),10)
bf=product(sub(has_image,1),100)
being sure to have in return always the same results of first
Hello,
I want to boost using multiple functions.
e.g.
{!boost b=recip(geodist(destination,1.293841,103.846487),1,1000,1000)
b=if(exists(query({!v=$b1})),100,0)
}
when I use above query Solr only considers second function.

Hi,
Use edismax query parser. boost parameter can take multiple values.
boost=recip(geodist(destination,1.293841,103.846487),1,1000,1000)
boost=if(exists(query({!v=$b1})),100,0)

if the functions never change, you could just index the computed value up
front and save cycles at query time -- but that's
to solve your needs.

apparently it does. what a great contriibution! got it to work with

Thanks!
single and double quote around the field name but didn't help.
Can field name contain hyphen in boot functions? How to do it? If not, where
do I find the field name special character restrictions?

Hi everyone,
I'm wondering if the MoreLikeThis handler takes the boost function
parameter into account for the scoring (hence the sorting I guess) of
the similar documents it finds.
Thanks for your help !

Hi -
Perhaps I'm missing something obvious, but it there a way to get values from
the user's request as arguments to boost functions in dismax?
I'm thinking about distance based weighting for search results, which
requires the user's x,y.

improve the score of recent documents? (I have a timestamp field in the
