• If you are trying to use Boolean operators, they must be ALL CAPS: (((("quality of works life") OR ("quality of worker life"))) OR ("quality of workers life")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"quality of works life\") OR (\"quality of worker life\"))) or (\"quality of workers life\"))".
• Removing quotes may allow a broader search: (((( quality of works life ) OR ( quality of worker life ))) or ( quality of workers life )).
