I need to filter elements from a list and show them in a result list. I made the following code:

var ele = [];

        $('.search').keyup(function(event) {

            var val = $(this).val().toUpperCase();

                $('.title').each(function(index, el) {
                    if($(this).find('a').text().toUpperCase().indexOf(val) != -1){
                        if(val != "" && val != null){
                                ele.push($(this).clone());
                        } 
                    }
                });

                $('.result').html(ele);
                ele = [];   
        });

This is the html:

<input  type="text" class="search">
<ul class="result"></ul>
<ul class="list">
<li class=""><a  href="">Elder</a>
    <ul>
        <li class=""><a href="">Cell</a>
            <ul>
                <li class="title"><a href="">Apolo</a></li>
                <li class="title"><a href="">megaman</a></li>
                <li class="title"><a href="">goku</a></li>
            </ul>
        </li>
    </ul>
</li>
<li>
    <ul>
        <li class="title"><a href=""> marcos</a></li>
        <li class="title"><a href=""> weslley</a></li>
    </ul>
</li>

The code works but for some reason I could not identify, it lists the same element that was already filtered while typing in the input. Where am I going wrong? Thanks!

He is copying the element to new list and then retrieving it himself, removes the class after copying:

    $('.search').keyup(function(event) {

        var val = $(this).val().toUpperCase();

        var ele = [];
        $('.title').each(function(index, el) {
            if($(this).find('a').text().toUpperCase().indexOf(val) != -1){
                if(val != "" && val != null){
                     var copy = $(this).clone();
                     copy.removeClass("title");
                     ele.push(copy);
                } 
            }
        });

            $('.result').html(ele);
    });
