Query

A word or phrase entered into a search engine in order to find information.

There are various techniques for maximising the effectiveness of a seach.

Enclosing the seach string in "quotation marks" will search for the string as a phrase

Use of a + sign means "and" so a search for "Arrse" + wiki will find all results with Arrse and wiki

On the other hand a -sign is useful as a "not".
