A search engine is a website, and associated back-end systems, used to find things on the internet. They can be extremely useful when researching preparedness, self-sufficiency, permaculture and any other subject, but there are privacy concerns associated using them.
Search engines often track user behavior for the purpose of advertising, but once the information is stored, it is accessible to organizations such as the NSA.
