• If you are trying to use Boolean operators, they must be ALL CAPS: ((cheo cua) OR (theo chu)) xang - tinh ban cua thong cong tinh ((toan tai) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: ((cheo cua) or (theo chu)) xang - tinh ban cua thong cong tinh ((toan tai) or (toan tap))*.
