• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"occasional prayers; occasional letter\") or (((\"occasional poems; occasional letter\") OR (\"occasional poems; occasional verse\"))))) or (\"occasional notess; occasional notes\"))".
• Removing quotes may allow a broader search: (((( occasional prayers; occasional letter ) or ((( occasional poems; occasional letter ) OR ( occasional poems; occasional verse ))))) or ( occasional notess; occasional notes )).
• Adding a wildcard symbol may retrieve word variants: (((("occasional prayers; occasional letter") or ((("occasional poems; occasional letter") OR ("occasional poems; occasional verse"))))) or ("occasional notess; occasional notes"))*.
