• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) tinh - hanh tranh cua thong thuong va thanh (thuy OR thu)~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) tinh - hanh tranh cua thong thuong va thanh (thuy or thu)~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (hoc thieu)) tinh - hanh tranh cua thong thuong va thanh (thuy or thu)*.
