www.verdocumentalesonline.com is a website I have developed using my brand http bot framework published on github. JohanBot. It can crawl over thousands of documentaries in spanish and filter the elements, like their categories or most important tags to create a good database where you can find the best documentaries.
I´ve created this because I´m a fanatic of WWII documentaries and never been able to find more than the 3 same documentaries that appear in the usual web browser (like google or yahoo). This system works 24/7 so, every new documentary will be there in less than a day. Today, this system its well acepted, recieving thousands of visits every day.
