• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chau tinh) OR (((cua tinh) OR (cua sinh)))) - hanh sinh cua nhung cong tac vang ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chau tinh) or (((cua tinh) OR (cua sinh)))) - hanh sinh cua nhung cong tac vang ban~".
• Adding a wildcard symbol may retrieve word variants: doi ((chau tinh) or (((cua tinh) OR (cua sinh)))) - hanh sinh cua nhung cong tac vang ban*.
