Perhaps you should try some spelling variations:
evidence syntheses » evidence hypothesis
evidence synopsis » science synopsis, eine synopsis, video synopsis
"evidence synthese" » "evidence scheme", "evidence sentence", "evidence southern"
"evidence systems" » "science systems", "valence systems", "reference systems"

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