Check the docs for min & max functions -- they don't do what you seem to think they do...
https://solr.apache.org/guide/solr/latest/query-guide/function-queries.html#max-function >> Returns the maximum numeric value of multiple nested functions or >> constants, which are specified as arguments: max(x,y,...) They also both have a pointer to the function that does do what you want... >> Use the field(myfield,max) syntax for selecting the maximum value of a >> single multivalued field. https://solr.apache.org/guide/solr/latest/query-guide/function-queries.html#field-function : Date: Tue, 2 Apr 2024 12:34:42 +0530 : From: govind nitk <govind.n...@gmail.com> : Reply-To: users@solr.apache.org : To: users@solr.apache.org : Subject: Using min/max value of field in boost query : : Hi, : : currently a working solution is like: : 1. First api call - take min, max value of numeric fields say price field : 2. In another api call to solr use it like : bq="div(sub(price,min_price),sub(max_price,sum(1,min_price)))^0.05" : : above is a working solution, but its two api based. : Can we use the min/max values in boost using function queries ? : : I tried with local param reference : ex. : min_price=min(price)&max_price=max(price)&bq="div(sub(price,$min_price),sub($max_price,sum(1,$min_price)))^0.05" : : This is not giving an error, but min_price is the same as price; so : sub(price,min_price) is zero and boost finally applied is zero. : : Is there any option to achieve this? : -Hoss http://www.lucidworks.com/
