Perhaps you should try some spelling variations:
"continuous hypothesis" » "continuum hypothesis", "continuity hypothesis", "continuum hypotheses"
"continuous synthesis" » "continuum synthesis", "discontinuous synthesis", "continents synthesis"
"continue hypothesis" » "continuum hypothesis", "continuity hypothesis", "continuum hypotheses"

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: (("continue hypothesis") OR ((("continuous hypothesis") OR ("continuous synthesis")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"continue hypothesis\") or (((\"continuous hypothesis\") OR (\"continuous synthesis\"))))".
• Removing quotes may allow a broader search: (( continue hypothesis ) or ((( continuous hypothesis ) OR ( continuous synthesis )))).
• Adding a wildcard symbol may retrieve word variants: (("continue hypothesis") or ((("continuous hypothesis") OR ("continuous synthesis"))))*.
