Have you ever noticed how Google interacts with you when you’re entering in a query? Either while you’re typing in your search or after submitting an irrelevant request, Google will recommend new search phrases and words that may be more relevant to what you’re looking for. It will correct spelling errors, suggest the most popular results, and automatically refine your search. This is called query refinement. Query refinement can also be manually done by the user: The user searches for something, doesn’t find what they’re looking for, and then searches again with a different query.
