downloading pages according to keyword's precense

[user357]

i would like to store only the specific pages from a newspaper where some specific words apear. its to get some bibliography for a scientific proyect. getting the url of those pages would be OK too. if i can imput a time period, that would be even better. i don't have programing knowledge, so i am struggling with this. not asking to be spoonfeed, but i would appreciate a lot if you can give me some insight on this.

Thanks for reading
