When searching, think of a word as a combination of letters and numbers. The search service needs to know how to separate words and numbers to find exactly what you want on the Internet. You can separate words using white space and tabs. You can link words and numbers together into phrases if you want specific words or numbers to appear together in your result pages. You can also create phrases using punctuation or special characters such as dashes, underscore lines, commas, slashes, or dots.
All searches are case insensitive and accent insensitive.
