Hey guyz, me again.

 

Basically i wrote a mini search engine in php, the problem is that i'm not sure how to order the query so that when searching say "google news", so that those with the 'title' "Google" are at the top.

 

The code:

<style>
ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
}
</style>

<form action="" method="GET">
  <label for="search">Query:</label>
  <input type="search" id="search" name="s" value="<?php echo $_GET['s']; ?>"><br>
  <input type="submit" value="Submit">
</form> 
<?php
include 'includes/config.php';

if(!empty($_GET))
{

    $search_string = $_GET['s'];
    $searchTerms = explode(' ', $search_string);
    $searchTermBits = array();
    foreach ($searchTerms as $term) {
        $term = trim($term);
        if (!empty($term)) {
            $searchTermBits[] = "keywords.word LIKE '%$term%'";
        }
    }

   print_r($searchTermBits);
   echo "<hr>";
   echo implode(' AND ', $searchTermBits);


    $query = $_GET['s'];

    $stmt = $pdo->prepare("SELECT links.title, links.URL, count(*) FROM links, link_word, keywords WHERE links.link_id = link_word.link_id AND link_word.key_id = keywords.key_id 
    AND ".implode(' OR ', $searchTermBits)." OR links.title LIKE ? GROUP BY URL");
    $stmt->execute(['%'.$query.'%']); 
    
    echo "<ul>";
    while ($row = $stmt->fetch()) {
        echo "<li><a href='".$row['URL']."'>".$row['title']."</a><li><small style='color: grey;'>".$row['URL']."</small>";
    }
    echo "</ul>";
}
?>

    <input type="submit" value="Submit">
</form>
<?php
include 'includes/config.php';

if (!empty($_GET)) {
    $query = $_GET['s'];
    $stmt = $pdo->prepare("SELECT title, URL, word FROM links, link_word, keywords WHERE links.link_id = link_word.link_id AND link_word.key_id = keywords.key_id AND MATCH(word) Against(?) OR MATCH(title) Against(?) GROUP BY URL");
    $stmt->execute([$query,  $query]);
    echo "<ul>";
    while ($row = $stmt->fetch()) {
        echo "<li><a href='" . $row['URL'] . "'>" . $row['title'] . "</a><li><small style='color: grey;'>" . $row['URL'] . "</small>";
    }
    echo "</ul>";
}
?>

:intoxicated: Perhaps there is an operator i could use?

SELECT ... ORDER BY LOCATE('google', title) = 0

EG

mysql> select * from test;
+----------+
| title    |
+----------+
| Google   |
| Fox      |
| CNN      |
| BBC      |
| Google 2 |
+----------+
5 rows in set (0.00 sec)

mysql> select * from test order by locate('google', title) = 0, title;
+----------+
| title    |
+----------+
| Google   |
| Google 2 |
| BBC      |
| CNN      |
| Fox      |
+----------+
5 rows in set (0.02 sec)
