 you'll find the documentation for query-log entries in the BIND
 Administrators Reference Manual (ARM), search for "The category phrase".
 "-" : query received was an iterative query (no-recursion, RD flag
 clear)
 "E" : query indicated support for EDNS0 on the sender side
 "D" : query had "DO" flag (DNSSEC OK) set, sender understands DNSSEC
 "C" : query had "CD" flag set (DNSSEC checking disabled), requestor
 wants to see all DNSSEC data, even if it does not validate
 Best regards
