Re: Solr upgrade|| LTR performance degrade
Hi Sachin,
We didn't get any update on this.
As an Apache Solr committer, I deeply care to provide the best software
possible to our users.
As a user, you can do your part in helping us understand possible bugs and
regressions.
Let us know and we can try to identify the regression and fix it!
Cheers

Re: Solr upgrade|| LTR performance degrade
Posted by Anna Ruggero <a....@sease.io>.
Hi Sachin,
I executed the same set of learning to rank queries (50 queries) with and
without feature extraction on the same Solr collection and on three
different Solr versions: 8.2, 8.7, and 8.8.
Here are the obtained results:
[image: image.png]
Since I cannot reproduce the degradation you are referring to, could you
give me some further information about the schema, documents,
models/features, and queries you are using?
It would really help.
Thank you,

Re: Solr upgrade|| LTR performance degrade
Posted by Alessandro Benedetti <a....@sease.io>.
So you noticed that the degradation was also there pre 8.8 (<8.8)?
Have you identified the first version having the regression?
Was it there with 8.7, this information would help a lot!

Hi Alessandro,
Sorry Missed the mail , the degradation continued to exist with various
higher versions. So we dropped the upgrade idea as we are in 8.2 version
solr.
