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

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 syntheses) OR (evidence hypothesis))) or (evidence systems))") OR ("evidence synthese")).
• Removing quotes may allow a broader search: (( ((((evidence syntheses) OR (evidence hypothesis))) or (evidence systems)) ) or ( evidence synthese )).
• Adding a wildcard symbol may retrieve word variants: (("((((evidence syntheses) OR (evidence hypothesis))) or (evidence systems))") or ("evidence synthese"))*.
