             Summary: SolrFeature fails to reject rq with missing efi (if used by fq)
                 Key: SOLR-10283
                 URL: https://issues.apache.org/jira/browse/SOLR-10283
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Christine Poerschke
            Assignee: Christine Poerschke


My intention had been to update the Solr Reference Guide's Learning To Rank section w.r.t. External Feature Information i.e. https://cwiki.apache.org/confluence/display/solr/Learning+To+Rank#LearningToRank-ExternalFeatureInformation based on the https://lists.apache.org/thread.html/17547c1487067804077b1933ccde28d68841ec1694f6776c5682f28e@%3Csolr-user.lucene.apache.org%3E user mailing list thread.

In the process I noticed that configuring a feature such as this
{code}
{
  "store" : "myEfiFeatureStore",
  "name" : "isPreferredManufacturer",
  "class" : "org.apache.solr.ltr.feature.SolrFeature",
  "params" : { "fq" : [ "{!field f=manu}${preferredManufacturer}" ] }
}
{code}
and then _not_ passing {{efi.preferredManufacturer=something}} is _not_ rejected and instead a score of 1.0 is returned for the feature.

This seems unexpected i.e. a bug.
