How to find information on the Internet?

Most information is found on the Internet by utilizing a search engines. A search engine is a web service that uses web robots to query millions of pages on the Internet and creates an index of those web pages. Users can then use these services to quickly and easily find the information they may be looking for.
When searching for information on the Internet keep the below things in mind.
Surround searches in quotes
If you are searching for multiple common words such as computer and help, it is a good idea to place quotes around the full search to get better results. For example, "computer help".
Be aware of stop words
Many search engines will strip out common words they refer to as stop words for each search that is performed. For example, instead of searching for why does my computer not boot, it'd search for documents with computer and boot. To help prevent these from being stripped surround the search with quotes.
Tip If stop words are not important, simply don't enter them into your search.
Familiarize yourself with booleans
Many search engines allow booleans, which can prevent results you many not want from being displayed. Although common booleans include "and", "or", and/or "not" most search engines have replaced these keywords with symbols. For example, if you were wanting to find computer help but didn't want to return any results for Linux computer help you'd type computer help -linux the -linux indicates to exclude any results containing the word linux.
