Function Query Parsing problem in Solr 5.4.1 and Solr 5.5.0

[Max Bridgewater]

Hi,

I have the following configuration for firstSearcher handler in
solrconfig.xml:


  <listener event="firstSearcher" class="solr.QuerySenderListener">
      <arr name="queries">
        <lst>
          <str name="q">parts</str>
          <str name="sort">score desc, Review1 asc, Rank2 asc</str>
        </lst>
        <lst>
          <str name="q">make</str>
          <str name="sort">{!func}sum(product(0.01,param1),
product(0.20,param2),  min(param2,0.4)) desc</str>
        </lst>
      </arr>
    </listener>

This works great in Solr 4.10. However, in solr 5.4.1 and solr 5.5.0, I get
the below error. How do I write this kind of query with Solr 5?


Thanks,
Max.
