postgres ignore -> orWhereHas - postgresql

Question

I Have 2 version app, one in local use MySQL and the other one is build in Heroku using PostgreSQL
The plan is to have search form that able to lookup data from different table
The table is books, writters, categories, and publishers
Here the controller
public function search(Request $request)
{
$keyword = $request->input('keyword');
// multiple query from different table
$query = Book::where('judul','like','%'.$keyword.'%')
->orWhere('label','like','%'.$keyword.'%')
->orWhere('isbn','like','%'.$keyword.'%')
->orWhere('status', 'like', '%'.$keyword.'%')
->orWhereHas('writter', function ($query) use ($keyword) {
$query->where('nama_penulis', 'like', '%'.$keyword.'%');
})
->orWhereHas('category', function ($query) use ($keyword) {
$query->where('nama_kategori', 'like', '%'.$keyword.'%');
})
->orWhereHas('publisher', function ($query) use ($keyword) {
$query->where('nama_penerbit', 'like', '%'.$keyword.'%');
})
;
$book_list = $query->paginate(5);
$pagination = $book_list->appends($request->except('page'));
$total_book = $book_list->total();
return view('dashboards.index', compact('book_list', 'keyword', 'pagination', 'total_book', 'nama_penulis'));
}
The form works like a charm on local (using my MySQL), but when I'm using Postgres the search form only able to fetch from books table.
I wonder what make postgres ignoring my code

Answer 1

someone on the Laracast explain to me that The problem is from like which is Case Sensitive for the Postgres, thats why my code didnt work.
If you have same issue, i recommend you to use ilike to make POstgres insensitive.
or you can try the alternative way by whereRaw instead.
