• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - ((hanh sinh) OR (hanh dinh)) ((cua chung) OR (cua nhung)) thong van thanh cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((hanh sinh) OR (hanh dinh)) ((cua chung) or (cua nhung)) thong van thanh cau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((hanh sinh) OR (hanh dinh)) ((cua chung) or (cua nhung)) thong van thanh cau*.
