   $doc1 = $updateQuery->createDocument();
   $doc1->id = 112233445;
   $doc1->cat = 'book';
   $doc1->name = 'A Feast For Crows';
   $doc1->price = 8.99;
   $doc1->inStock = 'true';
   $doc1->author = 'George R.R. Martin';
   $doc1->series_t = '"A Song of Ice and Fire"';
   $doc1->sequence_i = 4;
   $doc1->genre_s = 'fantasy';

4. Similarly, another document $doc2...
