how to paginate search results laravel code example

Example 1: laravel pagination with search filter

// if $id has value it will include "where('id','<',$id) else will return all"
$wells = DB::table('well_s')
        ->when($id, function ($query, $id) {
            return $query->where('id','<',$id);
        })
        ->paginate(20);

Example 2: laravel search and return record with pagination

//make sure that all your queries/builder has ->paginate and not a ->get() or 
//->first() then do {{ $var->links() }} in the blade

        if(empty($request->search)){
            $user = DB::table('users')->Paginate(15);
            return view('/users', ['user' => $user]);
        }else{
            $user = DB::table('users')->where('name', 'like', '%'. $request->search .'%')->Paginate(15);
            return view('/users', ['user' => $user]);
        }
