• If you are trying to use Boolean operators, they must be ALL CAPS: hoc trieu tinh - ((anh tang) OR (anh hoang)) cua dang rong thanh ((toan tap) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc trieu tinh - ((anh tang) or (anh hoang)) cua dang rong thanh ((toan tap) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: hoc trieu tinh - ((anh tang) or (anh hoang)) cua dang rong thanh ((toan tap) OR (toan ban))*.
