• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease hiv decrease owing decrease ) OR ( decrease NOT decrease working patterns ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease hiv decrease owing decrease ) OR ( decrease not decrease working patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease hiv decrease owing decrease ) OR ( decrease not decrease working patterns ))*.
