I'm new to irssi and I couldn't figure out one feature (or task).
I know I can use Page+Up/Down to scroll back and forth on the chat history. I also know I can use /lastlog to dump the whole chat history to console.
However, I don't know how to dump the chat history and grep certain pattern. For example, if I want to review conversation with someone named, user-a. My intuitive way is "grep user-a " so it will output all history in that window contain user-a.
Is there such a feature in irssi or irc in general?
