I ran performance tests with different query sets and the results look no good, it is adding to the latency around ~15% instead of reducing or even matching. Not sure if I am missing something in the config or it is an issue.
Here is an example query *without* WAND query parameter select?&fl=id,ext_id&start=0&q.op=OR&sort=score desc,ext_id asc&rows=10&q=white flowers card&defType=edismax&qf=keywords description title vs *With* WAND query parameter select?&fl=id,ext_id&start=0&q.op=OR&sort=score desc,ext_id asc&rows=10&q=white flowers card&defType=edismax&qf=keywords description title*&minExactCount=10* On Thu, Feb 1, 2024 at 8:36 AM rajani m <rajinima...@gmail.com> wrote: > Hi Ishan, > I have looked into that doc, and it looks like the solr version has to > be >8.8 and the config needed is to add the query parameter "&minExactCount=k" > where k is 10 or 100 depending on the accuracy of the first k docs. > > I ran a query performance test using an internal tool, with k set to 10 > and 100, which barely showed any difference in query time latency, I > didn't expect that so I was wondering if there is any configuration I > missed. > > I will run a couple more tests with different query sets meanwhile and dig > further into implementation of the feature to see if I am missing any > config here.
