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