Hello,
I am trying to use ltr together with cursorMarks on solr 7.7 and I am
getting the exception java.lang.ClassCastException:
org.apache.lucene.search.TopDocs cannot be cast to
org.apache.lucene.search.TopFieldDocs (full stacktrace below).
Browsing Jira I have found an issue that suggests I should always
include sort by score when combining reranking with cursorMarks.
However, that hasn't changed anything.
Is there anything I am missing?
o.a.s.s.HttpSolrCall null:java.lang.ClassCastException:
org.apache.lucene.search.TopDocs cannot be cast to
org.apache.lucene.search.TopFieldDocs
