not really sure where to put this question so random it is :thumb:
I understand how search engines (such as google or yahoo) work but can someone explain (or point me to something else that explains) how an internal search engine works?
I need to add a search engine to my companies internal sites that will only search our internal sites and not the outside world. So can anyone tell me how they do that (remembering Google or Yahoo won’t have access to an internal site) and perhaps does anyone know one I can even download and tinker with?
thanks
