Where like sql statement error

Hi,

I am trying to make a search in database with this code:
$this->template->museums = $this->database
->table(‘museum’)
->order(‘mu_id DESC’)
->limit(100)
->where( ‘museum.name like ?’, $search);

But it generates an error:

SELECT *
FROM museum
WHERE (museum.name like = ‘αρ’)
ORDER BY mu_id DESC
LIMIT 100

What I am doing wrong?
