• If you are trying to use Boolean operators, they must be ALL CAPS: tho ((chu nang) OR (chua nang)) - hang hang cua chung cong san ((toan tai) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tho ((chu nang) OR (chua nang)) - hang hang cua chung cong san ((toan tai) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: tho ((chu nang) OR (chua nang)) - hang hang cua chung cong san ((toan tai) or (toan cao))*.
