Perhaps you should try some spelling variations:
"christian history unix" » "christianity history unix", "christ history unix", "christian oratory unix", "christian history until", "christian history united", "christian history using"
"christian history und" » "christianity history und", "christ history und", "christian oratory und", "christian history under", "christian historie und", "christian history use"
"christian monitor union" » "christian ministry union", "christian monitor fusion", "christian monitor function", "christian monitor using"

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: (((("christian history unix") OR ("christian history und"))) OR ("christian monitor union")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"christian history unix\") OR (\"christian history und\"))) or (\"christian monitor union\"))".
• Removing quotes may allow a broader search: (((( christian history unix ) OR ( christian history und ))) or ( christian monitor union )).
• Adding a wildcard symbol may retrieve word variants: (((("christian history unix") OR ("christian history und"))) or ("christian monitor union"))*.
