1) which version of FunctionQuery are you using (from the solr repository or from a Jira issue attachment?) 2) what is hte full stacktrace? (ie: which function/line is throwing the Exception)
FunctionQuery supports explain just fine, not sure why you'd have problems, oh wait ... i see exactly what hte problem is... : The ms is a MultiSearcher. I read that ...this is the implemnetation for MultiSearcher... public Explanation explain(Weight weight,int doc) { throw new UnsupportedOperationException(); } ...it's got nothing to do with FunctionQuery. -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
