• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (doc hieu)) xanh - thanh tung ((vap nhung) OR (voi nhung)) long tinh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (doc hieu)) xanh - thanh tung ((vap nhung) OR (voi nhung)) long tinh toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (doc hieu)) xanh - thanh tung ((vap nhung) OR (voi nhung)) long tinh toan cau*.
