Hi Vaijanath, That would be great, thank you. And this will implement this formula ? RRFscore(d ∈ D) = sum r∈R 1 /(k + r(d) ) where r(d) = rank of d i.e. 1,2,n Thanks again and kind regards, Dan On Sat, 1 Apr 2023 at 17:41, Vaijanath Rao wrote: > Hi Dan, > > This was a long time ago,

Hi Dan, This was a long time ago, but I remember we use the recip function in solr to built it out. I will try to reach out to team to see if they can give me access to it. If not I will try to re-implement it and send it to you. This was thought for Solr-5/6. --Thanks and Regards Vaijanath On S

Hi Vaijanath, Was it a custom rank function, or custom rrf function for the sorting? Are you able to provide an example? Many thanks, Dan On Fri, 31 Mar 2023 at 17:42, Vaijanath Rao wrote: > We implemented it as a sort function instead of Q-parser. It was easier and > speed wise more efficient
