Perhaps you should try some spelling variations:
"general regulations" » "federal regulation", "gene regulation", "genetic regulation"
"general relative" » "general relations", "general operative", "general ergative"
"general relating" » "general relations", "general reading", "general regulation"
"general relation" » "general relations", "general revolution", "general circulation"
"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 relating"))) OR ((("general relation") OR ("general regulations")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"general relativity\") or (((((\"general relative\") OR (\"general relating\"))) or (((\"general relation\") or (\"general regulations\"))))))".
• Removing quotes may allow a broader search: (( general relativity ) or ((((( general relative ) OR ( general relating ))) or ((( general relation ) or ( general regulations )))))).
• Adding a wildcard symbol may retrieve word variants: (("general relativity") or ((((("general relative") OR ("general relating"))) or ((("general relation") or ("general regulations"))))))*.
