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