Thanks Blair, that works, here I was thinking filter() "filtered

It does. The difference between .filter() and .find() is that the
former searches through the matched elements, while the latter
searches through the *descendants* of the elements. I believe that
when you say:

you must have seen a result that was coincidentally what you
expected. Given the HTML:
<div class="foo bar">Test</div>
$('div.foo') selects the element
$('div').filter('.foo') selects the element
$('div').find('.foo') does not select the element
similarly,
$('.foo.bar') selects the element
$('.foo').filter('.bar') selects the element
$('.foo').find('.bar') does not select the element
If it appeared that .find() was selecting elements already in the
matched set, this is because an ancestor of the elements was already
in the matched set.
