Help needed in searching a sentence in the code

Hi All,

I have this code where user can search a song or the entire song title. It
looks like when a user search a single word its searching and giving the
proper results. However if the user wants to search the entire sentence its
not giving the proper results. For example let say I have searched for the
MJ's song "Earth Song", its giving me the proper results. However if I am
searching for the MJ's " Why You Wanna Trip On Me", its not giving me the
proper results. Below is the code:



<?php


//get data
$button = $_GET['submit'];
$search = $_GET['search'];

$s = 0;
$s = $_GET['s'];
if (!$s)
$s = 0;
$i = 0;

$e = 30; // Just change to how many results you want per page


$next = $s + $e;
$prev = $s - $e;




 if (strlen($search)<=2)


  echo "<br><table align='center'><tr><td><sup>&dagger;</sup><font
face='sana-serif' size='6'><font color='blue'><b><sup><a href='
http://localhost/searchengine/' style='text-decoration:
none'>MP3dom</a></sup></b></b></font><font face='sana-serif'
size='3'><sup>&trade;</sup></td><td><sup><form action='search.php'
method='GET'><input type='text' onclick=value='' size='50' name='search'
value='$search'> <input type='submit' name='submit'
value='Search'></form></td></tr></table> <table bgcolor='#0000FF'
width='100%' height='1px'><br /></table><table bgcolor='#f0f7f9'
width='100%' height='10px'><tr><td><div align='right'><b>Must be greater
then 3 chars</b></div></td></tr></table><p></sup>";
 else
 {
  echo "<br><table align='center'><tr><td>&dagger;<font face='sana-serif'

  //connect to database
  mysql_connect("localhost","root","");
  mysql_select_db("mp3");



   //explode out search term
   $search_exploded = explode(" ",$search);

   foreach($search_exploded as $search_each)
   {

        //construct query
    $x++;
    if ($x==1)
     $construct .= "name LIKE '%$search_each%'";
    else
     $construct .= " OR name LIKE '%$search_each%'";

   }

  //echo outconstruct
  $constructx = "SELECT * FROM data WHERE $construct";
