Hi,
Im going crazy over this. I cant seem to make a search using fulltext on a text in a foreign language (hebrew, arabic, russian etc..). Here is what I did:

1) create a table:

DROP TABLE IF EXISTS `test`;
CREATE TABLE `test` (
`Num` int(10) unsigned NOT NULL auto_increment,
`lang` text collate utf8_unicode_ci NOT NULL,
PRIMARY KEY (`Num`),
FULLTEXT KEY `Index_2` (`lang`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

Num Column is the ID and Lang Culumn is where I store the text.

2) Create a simple PHP script that will add data to the table:


<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>test</title>
</head>

<body>
<?php
if(isset($_REQUEST['var']))
{
$db_connect_id = mysql_connect("localhost", "username", "password");
if($db_connect_id)
{
$db_connect_id = mysql_select_db("powwow");
if($db_connect_id)
{
$sql = "insert into test set lang = '" . $_REQUEST['var']. "'";
mysql_query($sql);
echo "Done";

}
}else
echo "Error connecting to the DB;";
}
?>
<form action="/test.php">
<input type="text" name="var">
<input type="Submit">
</form>

</body>
</html>


3) Enter some hebrew or russian to the table (you can use google to find lots of text)

4) Make a search:

SELECT * FROM test WHERE MATCH (lang) AGAINST ('hebrew letters here' IN BOOLEAN MODE)

5) Got nothing back! It works with English though...


Any thoughts?
