Perhaps you should try some spelling variations:
"bounded variables" » "bounded variable", "bound variables", "bind variables"
"field variables" » "field variations"
"based variable" » "shared variable", "shared variables"

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: (("bounded variation") OR ((((("bounded variables") OR ("based variable"))) OR ("field variables")))).
• Removing quotes may allow a broader search: (( bounded variation ) or ((((( bounded variables ) or ( based variable ))) or ( field variables )))).
• Adding a wildcard symbol may retrieve word variants: (("bounded variation") or ((((("bounded variables") or ("based variable"))) or ("field variables"))))*.
