The + and - indicate whether the RA (Recursion Available) bit was or
wasn't set in the query. If it's set, the query probably came from a
name server that is saying it can do recursion and would be happy to
get a referral response. If it's not set -- indicated by the minus
sign -- the query probably comes from a stub resolver that expects the
name server to perform the resolution. EDNS0 queries are indicated by
the letter E in the logs.
