        <h3>Description</h3>
        <p><span>This function examines the</span> <span>parameters in the container to</span>
<span>find a match for the specified key.</span>
<span>The comparison is performed as if all</span>
<span>escaped characters were decoded first.</span></p>

<p><span></span></p>

<p><span>The search starts at `from`</span>
<span>and proceeds forward until either the</span>
<span>key is found or the end of the range is</span>
<span>reached, in which case `end()` is</span>
<span>returned.</span></p>

<h3>Example</h3>
<code>
url_view u( "?First=John&Last=Doe" );

assert( u.params().find( "first" ) != u.params().find( "first", ignore_case ) );
</code>
<h3>Complexity</h3>
<p><span>Linear in `this->buffer().size()`.</span></p>
