hieu nganh » vien nganh, hiem ngan, nghiep nganh
cap truong » cac truong, lap truong, cao truong

• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu nganh) OR (hieu manh)) - manh trung cap truong huong dan ((toan tai) OR (van ban))~.
• Adding a wildcard symbol may retrieve word variants: doc ((hieu nganh) or (hieu manh)) - manh trung cap truong huong dan ((toan tai) or (van ban))*.
