Overview of the Web

Crawlers to extract data

Search engines
Use a search engine when you have a clear idea what you are
looking for on a specific subject.
Use more search terms and more specific terms to give you
more specific results.
Search engines usually link your search terms with AND
(i.e. search for all terms).
Use quote marks to search for a specific phrase
(e.g. “climate change”).
