Search for different tables with multiple words - php

Question

I have a form
<form action="buscar.php" method="GET">
<input type="text" name="q" />
</form>
And my page where they show the results
<?php
require_once 'meekrodb.php';
$q = $_GET['q'];
$results = DB::query("SELECT * FROM product_description WHERE description like '%$q%'");
foreach ($results as $row) {
echo $row['name']."<br>";
}
?>
For example I have these phrases in description:
My car is big and green
My house is small and green
When I look for green, the 2 results come out, but if I look for a green house nothing comes out.
The problem is that I have to search for continuous text to work for example... My house is small...
How can I improve this query? Thank you

Try to explode GET variable.Or you can try to play with CONCAT
Explode
$q = $_GET['q'];
$word_array = explode(" ",$q);
$sqlnames="SELECT * FROM product_description WHERE";
$count = 0;
foreach($word_array as $value){
if($count == 0){
$sqlnames .= " description LIKE '" . $value ."'";
}
else{
$sqlnames .= " OR description LIKE '" . $value ."'";
}
$count = 1;
$sqlnames .= " OR description LIKE '" . $value ."'";
}
$sqlnames .="LIMIT 20";
CONCAT
(something like that)
$results = DB::query("SELECT * FROM product_description WHERE description LIKE '%$q%' OR description LIKE '%$q%' OR CONCAT(description, ' ', description ) LIKE '%$q%' LIMIT 20");
I have not tested this, but you can try to play.
