Perhaps you should try some spelling variations:
"continuous hypothesis" » "continuity hypothesis", "continuous synthesis", "continuum hypotheses"
"continues hypothesis" » "continuity hypothesis", "continuum hypotheses", "constituency hypothesis"
"contact hypothesis" » "continuity hypothesis"
"continuum hypothesis" » "continued hypothesis", "continue hypothesis"

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