• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((tieu sang) OR (tieu dung)) - hanh trong ca nhung ((cong va) OR (cong tac)) thuat cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu sang) or (tieu dung)) - hanh trong ca nhung ((cong va) OR (cong tac)) thuat cao".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu sang) or (tieu dung)) - hanh trong ca nhung ((cong va) OR (cong tac)) thuat cao*.
