I want to search database with maximum 3 words match with multiple fields and i am using given given code:

$hotel_name=trim($_GET['hotel_src_key']);
$search_type=trim($_GET['hotel_src']);
$pieces = explode(" ", $hotel_name);

//echo $pieces[1]; // piece2

$search1=$pieces[0];
$search2=$pieces[1]; 
$search3=$pieces[2];
echo $search1.$search2.$search3; 

if($search_type=="any hotel")
{
$rest ="WHERE hotel_name like '%$search1%' AND hotel_name like '%$search2%'AND hotel_name like '%$search3%' OR city like '%$search1%' AND city like '%$search2%' AND city like '%$search3%'";
}

if($search_type=="hotel city"){
$rest="WHERE city like '%$search1%' AND city like '%$search2%' AND city like '%$search3%'";
}
