Sql query not work

I am trying to filter data with search terms. But its not populate data. Any one can help me with this? Here is my code:

$query = Lesson::select('lesson.*')
				->join('lesson_language', 'lesson_language.lesson_id', 'lesson.id')
				->leftJoin('content', 'content.lesson_id', 'lesson.id')
                ->leftJoin('lesson_role', 'lesson_role.lesson_id', 'lesson.id')
				->leftJoin('lesson_brand', 'lesson_brand.lesson_id', 'lesson.id')
				->leftJoin('lesson_category', 'lesson_category.lesson_id', 'lesson.id');
            

            // filter by search term
            if(isset($request['search_term']) && $request['search_term'] != '') {
                $term = strtolower($request['search_term']);
                $term = str_replace('"', '', str_replace("'", '', $term));

                if((clone $query)->where('lesson_language.name', 'LIKE', "{$term}%")->count()) {
                    $query->where('lesson_language.name', 'LIKE', "{$term}%");
                }
                else {

                    $searchValues = preg_split('/\s+/', $term, -1, PREG_SPLIT_NO_EMPTY);
                    $query->where(function ($q) use ($term) {
//                        foreach ($searchValues as $subTerm) {
                            $q->orWhere('lesson_language.name', 'LIKE', "%{$term}%")
                                ->orWhere('lesson.content_skus', 'LIKE', "%{$term}%");
//                                ->orWhere('lesson.content_terms', 'LIKE', "%{$subTerm}%")
//                                ->orWhere('lesson.id', $subTerm);
//                        }
                    });
                    

                }
            }

This else statement not work. Here is the sql query for that.

select `lesson`.* from `lesson` inner join `lesson_language` on `lesson_language`.`lesson_id` = `lesson`.`id` left join `content` on `content`.`lesson_id` = `lesson`.`id` left join `lesson_role` on `lesson_role`.`lesson_id` = `lesson`.`id` left join `lesson_brand` on `lesson_brand`.`lesson_id` = `lesson`.`id` left join `lesson_category` on `lesson_category`.`lesson_id` = `lesson`.`id` where (`lesson_language`.`name` LIKE '%washer and dryer maintenance%') and `lesson`.`deleted_at` is null

Whats wrong with this code?
