• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - hanh ((((tang va) OR (tang vat))) OR (trang va)) nhung cong tap quan li.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - hanh ((((tang va) OR (tang vat))) or (trang va)) nhung cong tap quan li".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - hanh ((((tang va) OR (tang vat))) or (trang va)) nhung cong tap quan li*.
