I suppose it is and wouldn’t be too complex to do if it was just really a search bot really all it would be is a search egnine for search results with the ability to find queries based on posts(not that hard to break a post out of a thread), then search, and i suppose using a weight system get the best results and tell them.
thats in theory…it would tkae alot more to a computer becuase we’d have to strip out all the junk, then if it uses google or such make sure if its even relevent so in the end it would be quite complex since it would have to make sure it wasn’t just posting junk, and make sure it can even answer the question
