• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - ((hanh tranh) OR (hanh trinh)) ((cua dung) OR (cua dong)) trong tan toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((hanh tranh) or (hanh trinh)) ((cua dung) OR (cua dong)) trong tan toan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((hanh tranh) or (hanh trinh)) ((cua dung) OR (cua dong)) trong tan toan ban*.
