<p>Any ".search" file can be opened as search engine file, each line of which has one of the following formats:<br>
[Engine name]:[url without '%s' inside]<br>
[Engine name]:[url with '%s' as keyword]<br>
[Engine name]:POST:[post params with '%s' as keyword]:[url]</p>
<p>Limitations (they are here for performance reasons):</p>
<ul>
<li>The first engine in the file must be the first type that has no '%s' in the engine url.</li>
<li>Internal scheme engine urls (such as i:, d:, c:) must have '%s', since '%s' format is more general (only type 2 is allowed, since POST makes no sense for internal schemes).</li>
</ul>
