Is there a way to do something like q=hello+world&rq={!rerank reRankQuery=$rqq reRankDocs=100}&rqq=sort={!func}myFunc() desc ?
or even as simple as 1. http://localhost:8983/solr/0/select?q=edgengram:abc&wt=json&indent=true&debugQuery=true&rq={!rerank reRankQuery=$rqq reRankDocs=20}&rqq=sort=some_field desc I am not able to get the last part right. I dont think my rqq is right. --aj On Fri, Sep 18, 2015 at 12:00 PM Joel Bernstein <joels...@gmail.com> wrote: > The syntax would be something like this: > > q=hello+world&rq={!rerank reRankQuery=$rqq > reRankDocs=100}&rqq={!func}myFunc() > > I'm not sure if there is a test case demonstrating this but it should work. > > Joel Bernstein > http://joelsolr.blogspot.com/ > > On Fri, Sep 18, 2015 at 2:42 PM, Ajinkya Kale <kaleajin...@gmail.com> > wrote: > > > Is there a way I can issue a regular query with q and then apply > > functionQuery only on the top n documents of the result from q ? > > Applying functionQuery on all documents will be very expensive in my > case. > > I am not able to find a way to "rerank" only top N documents using > Function > > Query. > > > > --aj > > > > On Fri, Sep 18, 2015 at 5:04 AM Joel Bernstein <joels...@gmail.com> > wrote: > > > > > The ReRankQuery re-ranks the Top N documents of the main query based > on a > > > query.
