cua trong » cua truong, cua trung, qua trong
ho chieu » theo chieu, hoc thieu, mot chieu
mang cua » manh cua, dung cua, ban cua
dan than » dan chan, van than, dan toan

• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chieu)) xanh - hanh mang cua trong cong ((dan than) OR (ban than)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doi chieu)) xanh - hanh mang cua trong cong ((dan than) OR (ban than)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (doi chieu)) xanh - hanh mang cua trong cong ((dan than) OR (ban than)) cau*.
