AJAX for searching posts wordpress - ajax

Question

this is returning errors that occur when you try to load an url with [] in it(as far as I know)... I dont know why i am getting this errors... please help me correct the code below:
Errors:
Warning: strpos() expects parameter 1 to be string, array given in C:...\query.php on line 1718 <<<
Warning: preg_split() expects parameter 2 to be string, array given in C:...\query.php on line 1719 <<<
Warning: Invalid argument supplied for foreach() in C:...\query.php on line 1720 <<<
$("#submit").live("click", function() {
$("#form").submit(function() {
event.preventDefault();
var teste=$(this).serialize();
$.ajax({
type: "POST",
url: "./.../search.php",
data: teste,
success:function(data) {
$("#index_content").html(data);
}
});
});
});
Edited version that works :)
$("#submit").live("click", function() {
$("#form").submit(function() {
event.preventDefault();
teste = $('#form').serialize();
$.ajax({
type: "POST",
url: "./.../search.php",
data: { 'album-features': teste },
success:function(response) {
$("#index_content").html(response);
}
});
});
});

Since you are using wordpress, why not to use its built in ajax and send the request to admin-ajax.php. I see that you are sending it to search.php, which is not a good approach especially for security.
Write your php code to be executed in functions.php and add actions.
