Usage of double quotes around a set of words will help Google to search for the exact set of words without any change in the web pages. For example: [“lush green grass”] will give pages that contain the exact phrase.

Not or (-)
If you want to exclude a particular word or phrase use, “not” or “-“symbol. For example: [-lush green grass] will find pages that contain only [green grass].

Either/Or
All the words typed in the search box will be searched by Google. If you are looking for pages that contain one word or the other word, “Or” operator or “pipe symbol (l)” can be used. For example: [lush l green l grass] will bring pages that have either lush or green or grass.

Wildcard
This is useful only in certain domains and to find lyrics in a song. Wild card is the “*” symbol. For example: [“lush green grass”research*.edu] will show pages that contain educational information.

Keep it short
Use fewer words in order to get good and accurate results. When more words are used, the results get limited.

Similar Terms
The “~” symbol is used to get similar terms. For example: [~lush green grass – lush] will bring out pages that contain “plush green grass” and “dense green grass”.

Numrange
This feature searches for a range of numbers. For example: [best movies 2005..2010] will show best movies for each of the year from 2005 to 2010.

Definitions
This operator can be used to get a quick meaning or definition. For example: [define:lush] will give a number of definitions from different sources.

Apart from the above, the music operator can be used to return content related to music. Movie operator can be used to check the title of a movie along with the city, state or zip code. Advanced search can be used when you are not able to remember the Boolean operators. Always frame the question in the form of an answer to derive best results. There are other operators like Backlinks, vertical search, Site-specific, Unit converter and many more. These operators simplify your job and also help you in providing the accurate data that you require. Many people browse the Internet without having knowledge on the Boolean operators. If you are one among them, try using the operators. The beginners would have a tough time in getting the exact data from the search engine. I hope this article would be useful for you.
