Hello Dariusz,
Can you look into the solr logs for a stack trace or ERROR logs?

Subject: SOLR 7.2 and LTR
Hi,
I am using SOLR 7.0 and use the ltr parser.
The configuration I use works nicely under SOLR 7.0.0.
I am trying to upgrade to 7.2.0 but whenever I want to use my handler, I
get an exception:
"rq parameter must be a RankQuery"
The exact response is:
<lst name="error">
<lst name="metadata">
<str name="error-class">org.apache.solr.common.SolrException</str>
<str name="root-error-class">org.apache.solr.common.SolrException</str>
</lst>
<str name="msg">rq parameter must be a RankQuery</str>
<intname="code">400</int>
</lst>
My rq param is:
<str name="rq">{!ltr reRankDocs=25 model=myModel}</str>
I have simplified the model (Linear) to contain only single feature
"originalScore".
Works under 7.0, but when I run it with 7.2 - error.
Any hints on this?
