Perhaps you should try some spelling variations:
bulgarieniae » bulgarien, bulgariens, bulgaricae, bulgarienniae, vulgarisniae, vulgareniae
bulgarie » bulgarien, vulgaris, vulgare
bulgarian » hungarian
bulger » bulge, bulges

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((bulgarieniae OR bulgaria) OR ((bulgarie OR bulgarian) OR bulger))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((bulgarieniae or bulgaria) or ((bulgarie OR bulgarian) or bulger))*".
