Using $ this-> db-> like () in Codeigniter returns incorrect / missing results

I have an existing SQL query that works fine, as I want it:

$this->db->select('places.*, category.*')
            ->select('COUNT(places_reviews.place_id) AS num_reviews')
            ->select('(places_popularity.rating_1 + 2*places_popularity.rating_2 + 3*places_popularity.rating_3 + 4*places_popularity.rating_4 + 5*places_popularity.rating_5)/(places_popularity.rating_1 + places_popularity.rating_2 + places_popularity.rating_3 + places_popularity.rating_4 + places_popularity.rating_5) AS average_rating')
            ->from('places')
            ->join('category', 'places.category_id = category.category_id')
            ->join('places_reviews', 'places_reviews.place_id = places.id', 'left')
            ->join('places_popularity', 'places_popularity.place_id = places.id', 'left')
            ->where('places.category_id', $category_id)
            ->group_by('places.id')
            ->limit($limit, $offset)
            ->order_by($sort_by, $sort_order);

However, now I want to add a LIKE clause to the query, adding another line to the above to get:

$this->db->select('places.*, category.*')
            ->select('COUNT(places_reviews.place_id) AS num_reviews')
            ->select('(places_popularity.rating_1 + 2*places_popularity.rating_2 + 3*places_popularity.rating_3 + 4*places_popularity.rating_4 + 5*places_popularity.rating_5)/(places_popularity.rating_1 + places_popularity.rating_2 + places_popularity.rating_3 + places_popularity.rating_4 + places_popularity.rating_5) AS average_rating')
            ->from('places')
            ->join('category', 'places.category_id = category.category_id')
            ->join('places_reviews', 'places_reviews.place_id = places.id', 'left')
            ->join('places_popularity', 'places_popularity.place_id = places.id', 'left')
            ->where('places.category_id', $category_id)
                            ->like('places.name', $term)
            ->group_by('places.id')
            ->limit($limit, $offset)
            ->order_by($sort_by, $sort_order);

However, this gives me inaccurate results. For example, when I allow the search for the string $ term = "hong", and I have 3 rows where the column "name" matches "hong", i.e. (Hong Kong cafe, Hong Kong cafe, Ramen Hong), I will only receive (Hong Kong cafe, Hong Kong cafe). Now, if $ term = "hong kong", I get only one from the "Hong Kong cafe", and not both.

Another riddle me even more! There is a line called Dozo. When $ term = 'dozo', the result is not returned!
