I have the following search script, working fine, I would just like it to filter the search for words that have a minimum of 3 characters.
<script> $(function(){ var regex = new RegExp('[\?]', 'g'); //
repare a flag "g" de global, para substituir todas as ocorrências
$('input').bind('input', function(){
$(this).val($(this).val().replace(regex, '')); }); }) </script>
<input type="text" placeholder="Digite sua pergunta" autofocus name="query" size="16" style="font-size: 11 pt; color: #000000;
font-family: Verdana; font-variant: small-; border: 1 solid #000000">
</font></font> <font face="Verdana, Arial, Helvetica, sans-serif" size="2">
<input type="submit" value="Buscar" style="font-size: 8 pt; color: #000000; font-family: Verdana; font-variant: small-caps;
border: 1 solid #000000">
