$products = Product::where(function ($query) {
    $query->where('title', 'LIKE', '%laravel%')
        ->orWhere('title', 'LIKE', '%eloquent%');
})->get();

$products = Product::whereRaw('views > ? and votes > ?', [500, 50])->get();

$products = Product::whereRaw(DB::raw("store_id IN (SELECT member_id FROM member_permissions GROUP BY member_permissions.member_id WHERE role = 1)"))->get();

$products = Product::whereExists(function($query){
    $query->select(DB::raw(1))
        ->from('member_credits')
        ->whereRaw('member_credits.member_id = products.store_id')
        ->groupBy('member_credits.member_id')
        ->havingRaw("COUNT(*) > 3");
})->get();
// Any of the following may be used instead of Detail::whereExists
// ->orWhereExists(), ->whereNotExists(), ->orWhereNotExists()

$products = Product::whereIn('store_id', [1,2,3])->get();
// Any of the following may be used instead of Detail::whereExists
// ->orWhereIn(),

$products = Product::whereNotIn('store_id', function($query){
    $query->select('member_id')
        ->from('banned_members')
