Hello Vincenzo, I'm not getting your point:
> if I add an fq parameter the scale function still continues to work only on the q param . well, but the function actually refers to q param: scale(sum(price,query($q)), 0, 1). What's your expectation values of query($q) with "q":"popularity:(1 OR 7)"? I suggest to check it with fl=score On Tue, May 31, 2022 at 2:05 PM Vincenzo D'Amore <v.dam...@gmail.com> wrote: > Hi all, > > playing with the solr scale function I found a few corner cases where I > need to scale only the results set. > > I found a workaround that works but it does not seem to be viable, because > if I add an fq parameter the scale function still continues to work only on > the q param . > > For example with q=popularity:(1 OR 7): > > http://localhost:8983/solr/techproducts/select?q=popularity:(1 OR > 7)&rows=100&fl=price,scale(sum(price,query($q)), 0, 1) > > { > "responseHeader":{ > "status":0, > "QTime":1, > "params":{ > "q":"popularity:(1 OR 7)", > "fl":"price,scale(sum(price,query($q)), 0, 1)", > "rows":"100"}}, > "response":{"numFound":6,"start":0,"numFoundExact":true,"docs":[ > { > "price":74.99, > "scale(sum(price,query($q)), 0, 1)":0.099437736}, > { > "price":19.95, > "scale(sum(price,query($q)), 0, 1)":0.013234352}, > { > "price":11.5, > "scale(sum(price,query($q)), 0, 1)":0.0}, > { > "price":329.95, > "scale(sum(price,query($q)), 0, 1)":0.49875492}, > { > "price":479.95, > "scale(sum(price,query($q)), 0, 1)":0.7336842}, > { > "price":649.99, > "scale(sum(price,query($q)), 0, 1)":1.0}] > }} > > but moving the filter in fq: > > > http://localhost:8983/solr/techproducts/select?q=*:*&fq=popularity:(1%20OR%207)&rows=100&fl=price,scale(sum(price,query($q)),%200,%201) > > { > "responseHeader":{ > "status":0, > "QTime":8, > "params":{ > "q":"*:*", > "fl":"price,scale(sum(price,query($q)), 0, 1)", > "fq":"popularity:(1 OR 7)", > "rows":"100"}}, > "response":{"numFound":6,"start":0,"numFoundExact":true,"docs":[ > { > "price":74.99, > "scale(sum(price,query($q)), 0, 1)":0.034101862}, > { > "price":19.95, > "scale(sum(price,query($q)), 0, 1)":0.009072306}, > { > "price":11.5, > "scale(sum(price,query($q)), 0, 1)":0.0052296496}, > { > "price":329.95, > "scale(sum(price,query($q)), 0, 1)":0.15004548}, > { > "price":479.95, > "scale(sum(price,query($q)), 0, 1)":0.2182583}, > { > "price":649.99, > "scale(sum(price,query($q)), 0, 1)":0.29558435}] > }} > > > On the other hand, I was thinking of implementing a custom scale function > that by default works only on the current result set and not on the entire > collection. > > Any suggestions on how to solve this problem? > > Best regards, > Vincenzo > > > -- > Vincenzo D'Amore > -- Sincerely yours Mikhail Khludnev
