Thanks Christine. Unfortunately the change of parser doesn't seem to help either because the replacement of ` with " happens in the StreamExpressionParser itself ( https://github.com/apache/solr/blob/main/solr/solrj-streaming/src/java/org/apache/solr/client/solrj/io/stream/expr/StreamExpressionParser.java#L138 ), before sending to the handler (/qt).
It should ideally honor escaping for backtick and treat it as part of the token which it currently doesn't and that's the bug. I can submit a fix for this. Should I open a JIRA?
