• If you are trying to use Boolean operators, they must be ALL CAPS: (( h. (kent OR kunt) safer investment during ) OR ( h. joint social investment series ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( h. (kent OR kunt) safer investment during ) or ( h. joint social investment series ))~".
• Adding a wildcard symbol may retrieve word variants: (( h. (kent OR kunt) safer investment during ) or ( h. joint social investment series ))*.
