As：

"Computer adventure games"

In addition, exact matching queries using the number can also be used to achieve our specific search objectives. For example, in general, the "who", "I" is ignored by search engines as a stop-word, but sometimes when searching for special types of information, you must include these stop words (such as the "Who Am I" search for the movie name), and then we can have all the keywords in the "" number, You can force search engines to search for words that are deactivated as part of a phrase.

Through the combination of these logical symbols, can be composed of complex search conditions, such as "computer game"-adventure +new and so on, so that the query results more accurate.
