• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) xanh - hanh mang cua bang song van ((han tap) OR (han tai))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) xanh - hanh mang cua bang song van ((han tap) OR (han tai))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) xanh - hanh mang cua bang song van ((han tap) OR (han tai))*.
