Google Advanced Operator Search
Google allows the use of certain operators to help refine searches. The use of advanced operators is very simple as long as attention is given to the syntax. The basic format is:
operator:search_term
Notice that there is no space between the operator, the colon and the search term. If a space is used after a colon, Google will display an error message. If a space is used before the colon, Google will use your intended operator as a search term.

Searches within the title of the page which is displayed at the top of the bar.
intitle:Tech Bytes

This operator restricts the search only within a URL, or a web address of a document. This operator requires no other search arguments
