• If you are trying to use Boolean operators, they must be ALL CAPS: (((("open resource software") OR ("open resources software"))) OR ((("human resource software") OR ("human resonance software"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"open resource software\") or (\"open resources software\"))) or (((\"human resource software\") OR (\"human resonance software\"))))*".
• Removing quotes may allow a broader search: (((( open resource software ) or ( open resources software ))) or ((( human resource software ) OR ( human resonance software ))))*.
