I believe so, though I would test it out. You could try it out in http://splainer.io and confirm the scores are identical Cheers -Doug On Wed, Sep 23, 2015 at 12:10 PM, Vincenzo D'Amore wrote: > Hi, > > I have found in my code few boost functions like this one: > > bf=sum

boost functions

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

Thanks, I tried this but finally bf(additive boost) param worked well for me. Thanks for the help :) On Mon, Jun 30, 2014 at 5:14 PM, Ahmet Arslan wrote: > Hi, > > Use edismax query parser. boost parameter can take multiple values. > > &boost=recip(geodist(destination,1.293841,103.846487),1,10

Re: How do I use multiple boost functions?

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) On Monday, June 30, 2014 2:30 PM, Bhoomit Vasani wrote: Hello, I want to boost using multiple functions. e.g.

query parsers you can also use separate request parameters for each boost. See: https://cwiki.apache.org/confluence/display/solr/The+Extended+DisMax+Query+Parser -- Jack Krupansky -Original Message- From: Bhoomit Vasani Sent: Monday, June 30, 2014 7:30 AM To: solr-user@lucene.apache.

Caching Solr boost functions?

We're testing out a new handler that uses edismax with three different "boost" functions. One has a random() function in it, so is not very cacheable, but the other two boost functions do not change from query to query. I'd like to tell Solr to cache those boost queries

Facet sorting by boost functions

I'm using something along ?q=_val_:"product(field1,0.5)" and was wondering whether I could facet with category_id so that I get the single best document (product) for each category_id (not intrested in more than 5 of the best products in each of the highest-boosted category). Thanks!
