• If you are trying to use Boolean operators, they must be ALL CAPS: (("european concept history ser.") OR ((((("european concept history set.") OR ("europe concept history set."))) OR ("european concise history sir.")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"european concept history ser.\") or (((((\"european concept history set.\") OR (\"europe concept history set.\"))) or (\"european concise history sir.\"))))".
• Removing quotes may allow a broader search: (( european concept history ser. ) or ((((( european concept history set. ) OR ( europe concept history set. ))) or ( european concise history sir. )))).
• Adding a wildcard symbol may retrieve word variants: (("european concept history ser.") or ((((("european concept history set.") OR ("europe concept history set."))) or ("european concise history sir."))))*.
