• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - thanh trung ((cap nhung) OR (dap nhung)) cong ((manh toan) OR (thanh toan)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - thanh trung ((cap nhung) or (dap nhung)) cong ((manh toan) OR (thanh toan)) cao~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh trung ((cap nhung) or (dap nhung)) cong ((manh toan) OR (thanh toan)) cao*.
