Perhaps you should try some spelling variations:
"general operative" » "general operation", "general operating", "general preoperative"
"general relative" » "general relating", "general relations", "generalized relative"
"general ergative" » "general negatives", "general aggregative", "general cognitive"
"general relation" » "general relations", "general regulations", "general revolution"
"general relativity" » "general relatively"

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: (("general relativity") OR ((((((("general relative") OR ("general ergative"))) OR ("general operative"))) OR ("general relation")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"general relativity\") or (((((((\"general relative\") OR (\"general ergative\"))) or (\"general operative\"))) or (\"general relation\"))))".
• Removing quotes may allow a broader search: (( general relativity ) or ((((((( general relative ) OR ( general ergative ))) or ( general operative ))) or ( general relation )))).
• Adding a wildcard symbol may retrieve word variants: (("general relativity") or ((((((("general relative") OR ("general ergative"))) or ("general operative"))) or ("general relation"))))*.
