Perhaps you should try some spelling variations:
"tranquilizern und" » "tranquilizers _", "tranquilizer iv", "tranquilizers 1"
"tranquillizer gun" » "tranquilizer iv", "tranquilizer 3", "tranquilizer 5"
"tranquilizer und" » "tranquilize _", "tranquilizers _"
"tranquilizer 2.6" » "tranquilizer iv", "tranquilize _", "tranquilizers _"

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: (((((("tranquillizer gun") OR ("tranquilizer und"))) OR ("tranquilizern und"))) OR ("tranquilizer 2.6")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"tranquillizer gun\") OR (\"tranquilizer und\"))) or (\"tranquilizern und\"))) or (\"tranquilizer 2.6\"))".
• Removing quotes may allow a broader search: (((((( tranquillizer gun ) OR ( tranquilizer und ))) or ( tranquilizern und ))) or ( tranquilizer 2.6 )).
• Adding a wildcard symbol may retrieve word variants: (((((("tranquillizer gun") OR ("tranquilizer und"))) or ("tranquilizern und"))) or ("tranquilizer 2.6"))*.
