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