I think this is a great example for Enumerable [1] usage.
Try the code below. I have no time to test it properly at the moment,
but it should work. If not, read about Enumerable and you should be
able to correct me.
var list =
$('search').down('tbody').select('tr > td:nth-child(1)');
list.map( function(td) {
//lets map each td to its concent
return tr.down('a').innerHTML;
}).uniq().findAll(function(content) {
//test if there was 'a' element and if it contains what it
//should. I assume the sk is defined.
return (content && content.toLowerCase().include(
sk.toLowerCase()));
}).each(function (content) {
$('distinct').insert(content);
});

Hope this helps.
