Perhaps you should try some spelling variations:
german world » german word, german words, german works
fighter aces » fighters tales, fighter needs, fighter a
die night » die nicht, date night, die height
ii night » ii nicht, viz night, big night
de night » de knight, mode night, one night

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: list of german world war ((ii night) OR (((die night) OR (de night)))) fighter aces.
• The words AND, OR and NOT may confuse the search; try adding quotes: "list of german world war ((ii night) or (((die night) OR (de night)))) fighter aces".
• Adding a wildcard symbol may retrieve word variants: list of german world war ((ii night) or (((die night) OR (de night)))) fighter aces*.
