Perhaps you should try some spelling variations:
"topographic" » "topography", "ethnographic"
"topographien" » "topographies", "topographica", "topographischen", "topographyn", "topographicaln", "ethnographien"
"topographie" » "topography", "topographical", "ethnographie"
"monographien" » "monographs", "monograph"

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