search feature not work for certain words - php

Question

The problem I faced is when search word "anti" it will display the product but when search based words "anti wrinkle" mentioned no search result. Please refer below for the code and advice what do I missed.
$search_output = '';
if(isset($_POST['search'])) {
$searchsql = $_POST['search'];
$searchsql = preg_replace('#[^a-z 0-9?!#-]#i', '', $searchsql);
$query = mysql_query("SELECT tb_spa_prd.*, tb_spa_prd_cat.spa_prd_cat FROM tb_spa_prd AS tb_spa_prd INNER JOIN tb_spa_prd_cat ON tb_spa_prd.spa_prd_cat_id = tb_spa_prd_cat.spa_prd_cat_id WHERE spa_prd_cat LIKE '%$searchsql%' or spa_prd_code LIKE '%$searchsql%' or spa_prd_name LIKE '%$searchsql%'") or die ("Could no search!");
$count = mysql_num_rows($query);
if($count == 0) {
$search_output .= '<tr>
<td colspan="9" style="text-align: center">There was no search results!</td>
</tr>';
} else {
$row_no = 1;
while($row = mysql_fetch_array($query,MYSQL_ASSOC)) {
$spa_prd_id = $row["spa_prd_id"];
$spa_prd_cat = $row["spa_prd_cat"];
$spa_prd_code = $row["spa_prd_code"];
$spa_prd_name = $row["spa_prd_name"];
$spa_prd_vlm = $row["spa_prd_vlm"];
$spa_prd_qty = $row["spa_prd_qty"];
$spa_prd_crt_date = $row["spa_prd_crt_date"];
$spa_prd_crt_usr = $row["spa_prd_crt_usr"];
$search_output .= '<tr>
<td>'.$row_no++.'</td>
<td>'.$spa_prd_cat.'</td>
<td>'.$spa_prd_code.'</td>
<td>'.$spa_prd_name.'</td>
<td>'.$spa_prd_vlm.'</td>
<td>'.$spa_prd_qty.'</td>
<td>'.$spa_prd_crt_date.'</td>
<td>'.$spa_prd_crt_usr.'</td>
<td><a href=\'edit_spa_prd.php?spa_prd_id='.$spa_prd_id.'\'>Edit</a> | <a href=\'delete_spa_prd.php?spa_prd_id='.$spa_prd_id.'\'>Delete</a></td>
</tr>';
} // close while loop
}
}

You can try explicitly including a LIKE predicate for each search term like this:
$searchsql = $_POST['search'];
$terms = explode(" ", $searchsql);
$likecols = array("spa_prd_cat", "spa_prd_code, "spa_prd_name");
$likesql = "";
foreach ($likecols as $likecol) {
for ($i = 0; $i < count($terms); ++$i) {
if ($likecol == "spa_prd_cat" && $i == 0) {
$likesql = "spa_prd_cat LIKE $terms[0]";
}
else {
$likesql .= " OR $likecol LIKE $terms[$i]";
}
}
}
$querystr = "SELECT tb_spa_prd.*, tb_spa_prd_cat.spa_prd_cat FROM tb_spa_prd AS tb_spa_prd INNER JOIN tb_spa_prd_cat ON tb_spa_prd.spa_prd_cat_id = tb_spa_prd_cat.spa_prd_cat_id WHERE ";
$querystr .= $likesql;
$query = mysql_query($querystr) or die ("Could no search!");
