How to use a lookup file to search for ip addresses in my logs?

[jcaron9999a]

I have a lookup file called ipaddress.csv.  The column title in the file is ipaddress.  I want to search my logs for all of these ip addresses.  I know I need to use inputlookup to get the addresses from the file, but I can't figure out how to then feed them to a search.

Thanks in advance

This is a subsearch, where the inputlookup is used as a subsearch

your_base_search [ | inputlookup ipaddress.csv | fields ipaddress ]

Here the subsearch ([] section) runs first and returns a structured piece of text with 

ipaddress=A OR ipaddress=B OR ipaddress=C

and so on to the outer search. Note that if your ip address field in your main index search is something different, then before the fields command, you should do a rename

| rename ipaddress as your_ip_field

Thanks!  That did the trick.
