Hi Jack Krupansky,
Thank you for your reply. I would like to know how you got the error
logging? Is there any special flag I have to turn on? Because I don't see
it in my solr.log even after switching the log level to DEBUG.
<str name="msg">org.apache.solr.**search.SyntaxError: Cannot parse 'id:*
AND text:()': Encountered " ")" ") "" at line 1, column 15.
Thanks
