Perhaps you should try some spelling variations:
vulgariae » vulgarise, bulgaricae, vulgaridad
bulgariae » bulgaricae, bulgarian, bulgarians
vulgarisee » vulgarise, vulgarises, vulgaris
bulgariaien » bulgarian, bulgarien, bulgaristen
bulgarie » bulgarien, bulgarian, vulgaris
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: ((((vulgariae OR bulgariae) OR vulgarisee) OR bulgariaien) OR ((bulgarie OR bulgaria) OR bulger))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((vulgariae OR bulgariae) or vulgarisee) or bulgariaien) or ((bulgarie or bulgaria) or bulger))*".
