How can I search for a certain word in all of 4chan? Let's say I wanted to see all threads of all boards (/b/, /g/, /vg/... just all of them) WHICH have the word "peanut" in the OP, is there a tool anywhere which can help me with this?
I think it might be rather easy to make that tool in case it doesn't exist but I only know how to do stuff in Processing and I'm new to programming, so it would be cool if someone can link me to this.
Things that would make it better:
>live functionality, always refreshing itself maybe around every minute so that I can see the threads I might miss
>showing the OP picture too like in the catalog
>every time a new thread with the word is made it makes a sound
