Query not following rules!!

Just exploring options. I don't see anything that jumps out at me, so...

If you comment out the or_like condition, do you get all records for 'tech1', subject to the limit of 100?

Code:

$this->db->where('added_by', $tech);
//$this->db->or_like($infoarray);
$this->db->limit(100);
$this->db->order_by('date_created', 'DESC');
$query = $this->db->get('item_history');
return $query->result();
