Perhaps you should try some spelling variations:
"constrained hypothesis" » "constraint hypothesis", "constrained synthesis", "constraint hypotheses"
"continued hypothesis" » "continuity hypothesis", "continuum hypotheses", "constituency hypothesis"
"continuum hypothesis" » "continuous hypothesis", "continue hypothesis", "continues 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: (("continuum hypothesis") OR ((("continued hypothesis") OR ("constrained hypothesis")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"continuum hypothesis\") or (((\"continued hypothesis\") OR (\"constrained hypothesis\"))))".
• Removing quotes may allow a broader search: (( continuum hypothesis ) or ((( continued hypothesis ) OR ( constrained hypothesis )))).
• Adding a wildcard symbol may retrieve word variants: (("continuum hypothesis") or ((("continued hypothesis") OR ("constrained hypothesis"))))*.
