• If you are trying to use Boolean operators, they must be ALL CAPS: (("handbook of experimentellen pharmakologie") OR ((("handbook of experimentellen pharmacologic") OR ("handbook of experimentelle pharmakologie")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"handbook of experimentellen pharmakologie\") or (((\"handbook of experimentellen pharmacologic\") OR (\"handbook of experimentelle pharmakologie\"))))".
• Removing quotes may allow a broader search: (( handbook of experimentellen pharmakologie ) or ((( handbook of experimentellen pharmacologic ) OR ( handbook of experimentelle pharmakologie )))).
• Adding a wildcard symbol may retrieve word variants: (("handbook of experimentellen pharmakologie") or ((("handbook of experimentellen pharmacologic") OR ("handbook of experimentelle pharmakologie"))))*.
