How to write union query in Laravel?

I'm using laravel 5.0 and I have mysql query:

SELECT surat_masuk.id_surat,
surat_masuk.nomor_surat
FROM surat_masuk
WHERE ! EXISTS (SELECT *
FROM file_replace
WHERE id_surat_lama = surat_masuk.id_surat)
AND surat_masuk.id_jenis_surat = '6'
AND surat_masuk.deleted = '0'
UNION
SELECT id_surat_lama
FROM file_replace
WHERE id_surat_baru = '38'


And I write that in my laravel code into:

$nomor_surat1 = DB::table('surat_masuk')->select('id_surat', 'nomor_surat')
->where('id_jenis_surat', '=', $id_jenis_surat)
->where(function ($query) {
$query->where('masa_berlaku_to', '>=', date('Y-m-d'))
->orwhere('masa_berlaku_to', '=', '0000-00-00');
})
->whereExists(function ($query) {
$query
->from('file_replace')
->where('id_surat_lama', '==', 'surat_masuk.id_surat');
})
->where('deleted', '=', '0');

$nomor_surat = DB::table('file_replace')->join('surat_masuk', 'file_replace.id_surat_lama', '=', 'surat_masuk.id_surat')
->select('id_surat_lama', 'nomor_surat')
->where('id_surat_baru', '=', $id_surat_baru)
->union($nomor_surat1)->get();


But I've got nothing showed. Do you know where is the mistakes?

Answer

Well, I finally using raw query..

$results = DB::select( DB::raw("SELECT * FROM some_table WHERE some_col = '$someVariable'") );
