Perhaps you should try some spelling variations:
"johannes van beethoven" » "johannes de beethoven", "johannes von beethoven", "johannes c beethoven", "johannes _ beethoven"
"johannes a beethoven" » "johannes _ beethoven", "johannes b beethoven", "johannes de beethoven", "johannes c beethoven", "johannes f beethoven"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"johannes van beethoven\") OR (\"johannes a beethoven\"))".
• Removing quotes may allow a broader search: (( johannes van beethoven ) OR ( johannes a beethoven )).
• Adding a wildcard symbol may retrieve word variants: (("johannes van beethoven") OR ("johannes a beethoven"))*.
