Yes, but you can't find textnodes, only elements. If you had
<td><span>History</span></td> then $(':contains(History)','td') would
work.

For filter functions you need to return true or false, you're
returning a jQuery object:
$('td').filter(function(){
return $(this).is(':contains(History)') //is() returns true/
false
});
But in this case you can use a selector in filter() directly:
$('td').filter(':contains(History)')
which doesn't make sense because it's exactly the same as
$('td:contains(History)')
You don't really need to use a context in this situation.
Hope I'm not confusing you.
