delay

The delay in milliseconds between a keystroke in the input element occurs and a search for the string entered is performed. Defaults to 200.

If you are working with local data, you may put 0 to make the search faster.

<input id="autocomplete"></input>

<script type="text/javascript">

     $(function () {
       $("#autocomplete").shieldAutoComplete({
            dataSource: {
                data: myData
            },
            delay: 300
        });
    });
