Combining AND/OR eloquent query in Laravel

Question

How can I write following or similar kind of queries using Eloquent?

SELECT * FROM a_table WHERE (a LIKE %keyword% OR b LIKE %keyword%) AND c = 1 AND d = 5

Answer 1

In Laravel 5.1+ this will also do the job and looks cleaner:

Model::where(function($query) {
    $query->where('a', 'like', 'keyword');
    $query->or_where('b', 'like', 'keyword');
})->where('c', '=', '1')->get();
