"search" implies making a detailed effort to find something specific, while "browse" means you are going through randomly looking at things without a specific goal in mind. You go to the library to browse the fiction section. You can also go to search for a biography of Ghandi.

"Browse", in its most literal sense, means to eat grass and young shoots. Grazing animals such as cows and sheep are called browsing animals. So, the use of "browse" when looking through books or the internet is figurative, Aside from that, Judy's explanation is exactly what you need to know: search is specific, and browse is without an aim in mind.

Judy gave a good answer. Here's a common way to use the word "browse." Imagine you go to a store. You're not looking for anything in particular, but you want to see what's there. The saleslady says, "May I help you find something?" You can reply, "No, thank you. I'm just browsing."
