        <h3>Synopsis</h3>
        <div>
            <code>
                            </code>
        </div>
        <pre class="source-code cpp">
            template<class StringToken = string_token::return_string>
StringToken::result_type

        <h3>Description</h3>
        <p><span>If this contains a query, it is returned</span> <span>as a string (which may be empty).</span>
<span>Otherwise, an empty string is returned.</span>
<span>Any percent-escapes in the string are</span>
<span>decoded first.</span>
<span></span>
<span>When plus signs appear in the query</span>
<span>portion of the url, they are converted</span>
<span>to spaces automatically upon decoding.</span>
<span>This behavior can be changed by setting</span>
<span>decode options.</span></p>

<h3>Example</h3>
<code>
assert( url_view( "/sql?id=42&name=jane%2Ddoe&page+size=20" ).query() == "id=42&name=jane-doe&page size=20" );
</code>
<h3>Complexity</h3>
<p><span>Linear in `this->query().size()`.</span></p>

<h3>Exception Safety</h3>
<p><span>Calls to allocate may throw.</span></p>

<h3>BNF</h3>
<code>
query           = *( pchar / "/" / "?" )

query-param     = key [ "=" value ]
query-params    = [ query-param ] *( "&" query-param )
</code>
