search returns: Can't find FULLTEXT index matching the column list


Recommended Posts

using the source from the tutorial on this website, i have attempted to make a search for a table on one of my  mysql databases.

 

it returns "Can't find FULLTEXT index matching the column list"

 

not sure what it means, i googled for it and searched from problems, i can't find the problem!

 


<html>
<head><title>Search</title></head>
<body>

<?php

//vars for host username password db table and all that junk

// Full-Text Search Example
// Conect to the database.
$cnx = mysql_connect($host, $username, $password) or die ("Could not connect");
mysql_select_db($db,  $cnx) or die (mysql_error());

// Create the search function:

function searchForm()
{
  // Re-usable form
  
  // variable setup for the form.
  $searchwords = (isset($_GET['words']) ? htmlspecialchars(stripslashes($_REQUEST['words'])) : '');
  $normal = (($_GET['mode'] == 'normal') ? ' selected="selected"' : '' );
  $boolean = (($_GET['mode'] == 'boolean') ? ' selected="selected"' : '' );
  
  echo '<form method="get" action="'.$_SERVER['PHP_SELF'].'">';
  echo '<input type="hidden" name="cmd" value="search" />';
  echo 'Search for: <input type="text" name="words" value="'.$searchwords.'" /> ';
  echo 'Mode: ';
  echo '<select name="mode">';
  echo '<option value="normal"'.$normal.'>Normal</option>';
  echo '<option value="boolean"'.$boolean.'>Boolean</option>';
  echo '</select> ';
  echo '<input type="submit" value="Search" />';
  echo '</form>';
}


// Create the navigation switch
$cmd = (isset($_GET['cmd']) ? $_GET['cmd'] : '');

switch($cmd)
{
  default:
    echo '<h1>Search Database!</h1>';
    searchForm();
  
  break;
  
  
  case "search":
    searchForm();
    echo '<h3>Search Results:</h3><br />';
    
    $searchstring = mysql_escape_string($_GET['words']);
    switch($_GET['mode'])
    {
      case "normal":
        $sql = "SELECT id, updated_by, updated_on, pagecontent, //these are in my database
               MATCH(updated_on, updated_by, pagecontent) //i think the problem is in this switch
               AGAINST ('$searchstring') AS score FROM $table 
               WHERE MATCH(updated_by, updated_on, pagecontent) 
               AGAINST ('$searchstring') ORDER BY score DESC";
      break;
      
      case "boolean":
        $sql = "SELECT id, updated_by, updated_on, pagecontent, 
               MATCH(updated_on, updated_by, pagecontent) 
               AGAINST ('$searchstring' IN BOOLEAN MODE) AS score FROM $table 
               WHERE MATCH(updated_on, updated_by, pagecontent) 
               AGAINST ('$searchstring' IN BOOLEAN MODE) ORDER BY score DESC";
      break;
    } 
    
    // echo $sql;
    
    $result = mysql_query($sql) or die (mysql_error());
    
    while($row = mysql_fetch_object($result))
    {
      echo '<strong>Date created: '.stripslashes(htmlspecialchars($row->updated_on)).'</strong><br />';
      echo '<p>'.stripslashes(htmlspecialchars($row->pagecontent)).'</p>';
      echo '<hr size="1" />';
    }
  break;
}
?>

</body>
</html>

I typed your error into google and this was the first result: http://www.iwebsupport.com/know/article.php?id=004

 

I don't know if that is the specific source you are using, but it mentions that you need to have a field in your database called "fulltext."
