Perhaps you should try some spelling variations:
"evidence hypothesis" » "evidence synthesis", "science hypothesis", "violence hypothesis"
"evidence synthese" » "evidence synthesis", "evidence systems", "evidence sentence"
"evidence scheme" » "evidence science", "evidence some", "evidence seems"

Try widening your search to All Fields.

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