Removing ports utilizing "between" X and Y

Hello,

I am trying to use a "between" function. For instance:

index=main sourcetype=":cisco_asa" | where dest_port > 1024 AND dest_port!= 8000-8999 etc etc

Obviously "8000-8999" does not work. Any help would be appreciated.

Thank You,

Tim

The way to search for dest_port!=8000-8999 would be to split it like this: dest_port<8000 OR dest_port>8999. Also, you don't need to push that into a where clause; it can (and should) go directly into your base search for better efficiency:

index=main sourcetype=":cisco_asa" dest_port > 1024 AND (dest_port<8000 OR dest_port>8999)
