• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"chau ky la tinh.\") OR (((\"chau y ha tinh.\") OR (\"hau y ha tinh.\"))))".
• Removing quotes may allow a broader search: (( chau ky la tinh. ) OR ((( chau y ha tinh. ) OR ( hau y ha tinh. )))).
• Adding a wildcard symbol may retrieve word variants: (("chau ky la tinh.") OR ((("chau y ha tinh.") OR ("hau y ha tinh."))))*.
