The query component

After the final segment of the path, the URL may contain an optional query component, indicated by the presence of the question mark character (?) delimiter. The query component allows users to specify additional parameters for more specific results from the requested resource. Each different query comes in the form of a parameter, the equals sign (=) delimiter, and the requested value of the query parameter. Finally, each parameter is delimited by either a semi-colon (;) or ampersand (&) delimiter between any two query parameters and their values.
