Perhaps you should try some spelling variations:
vulgare » vulgar, vulgaris, vulgarly
bulgar » vulgar, bulger, bulgaria
bulgare » vulgare, bulgere, bulgariae, bulgarie, bulgarien, bulgaria
bulgariae » vulgariae, bulgeriae, bulgariaiae, bulgaricae, bulgaria, bulgarian

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: ((bulgaars OR vulgare) OR (bulgar OR (bulgare OR bulgariae))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((bulgaars or vulgare) or (bulgar or (bulgare OR bulgariae)))".
• Adding a wildcard symbol may retrieve word variants: ((bulgaars or vulgare) or (bulgar or (bulgare OR bulgariae)))*.
