Search operators are query language features that give users the ability to specify how they want their search results to be ranked. By default, most search engines use a simple ranking algorithm that takes into account factors like the frequency of keywords in the query and on the webpage, along with the number and quality of incoming links to the webpage. However, this doesn't always give users the most relevant results, which is why many search engines allow users to employ search operators. Please check advanded search operators in this article.
