• If you are trying to use Boolean operators, they must be ALL CAPS: (("world conference amast rabies 2001") OR ((("world conference acisp rabies 20") OR ("world conference acisp rabies 10")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"world conference amast rabies 2001\") or (((\"world conference acisp rabies 20\") OR (\"world conference acisp rabies 10\"))))".
• Removing quotes may allow a broader search: (( world conference amast rabies 2001 ) or ((( world conference acisp rabies 20 ) OR ( world conference acisp rabies 10 )))).
• Adding a wildcard symbol may retrieve word variants: (("world conference amast rabies 2001") or ((("world conference acisp rabies 20") OR ("world conference acisp rabies 10"))))*.
