When a quite long string is put to Filters property of Query object, it throws Invalid URI: The Uri string is too long exception during serialization. Here is a stack trace:

   at System.UriHelper.EscapeString(String input, Int32 start, Int32 end, Char[] dest, Int32& destPos, Boolean isUriString, Char force1, Char force2, Char rsvd)

The usage of Uri.EscapeDataString in this method
