Interpreting bind logging queries

[Alex]

Hi,

I have a bind-9.8.3 fc16 system and would like to know more about how
logging works. How can I determine whether the results were from the
local cache or it was actually necessary to query a remote server to
return a response?

Given a query log entry such as:

20-Jun-2012 13:23:50.023 queries: client 127.0.0.1#47286: query:
factoryfitpartscorp.info IN A + (127.0.0.1)

How can I determine if this request was made to the server for this
domain or if it had previously been queried and is retrieving it from
a cache?

Can you point me to where I can find information about interpreting query logs?

Thanks,
Alex
