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