: XML Parsing Error: mismatched tag. Expected: </HR>. : : Location: http://localhost:8080/solrServlet/searchServlet?query=%D9%85%D8%AD%D9%85%D8%AF&cmdSearch=Search%21 this doesn't look like a query error .. and that doesn't look like a solr URL, this looks something you have in front of Solr. : </head><body><h1>HTTP Status 400 - Query parsing error: Cannot parse : '????': '*' or '?' not allowed as first character in that looks like a Solr error. i'm guessing that your app isn't dealing with the UTF8 correctly, something is substituting "?" characters in place of any character it doesn't understand - and Solr thinks you are trying to do a wildcard query. have you tried querying solr directly (in your browser or using curl) for your arabic word? -Hoss
