I try do a query on Solution object. It complains that SolutionNote cannot be filtered in query call. Does anyone know how to make it work? Thanks.

binding.query("select SolutionName, SolutionNote from Solution where Key_Words__c like '%" + keyWord + "%' or SolutionName like '%" + keyWord +"%'");

{"INVALID_FIELD: \nor SolutionName like '%du%' or SolutionNote like '%du%'\n                               ^\nERROR at Row:1:Column:111\nfield 'SolutionNote' can not be filtered in query call"}
