Boolean
operator
Example query string
Example explanation
AND
TcpPort:80 AND Protocol:http
Two query terms are used to find all
standard web traffic. If web testing
occurs on Port 8080, then it would not
be a match since both query terms
would not be true.
OR
Collection:yahoo* OR
Collection:cnn* OR Collection:msn*
Three query terms are used to limit
the results to results from the Yahoo,
CNN, and MSN document collections
in the forensics repository.
NOT
ApplicationProtocol:http AND NOT
ServerTcpPort:(80 OR 8080 OR 81)
Searches for traffic with non-standard
port usage. The first query term looks
for standard HTTP traffic and the
second query term eliminates all traffic
that is using accepted HTTP ports.
