• Performing a fuzzy search may retrieve terms with similar spellings: vu ((sang ky) or (dang y)) nang ma hoi. ((hieu viec) OR (sieu viet)) cac luc va hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sang ky) OR (dang y)) nang ma hoi. ((hieu viec) OR (sieu viet)) cac luc va hanh vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sang ky) or (dang y)) nang ma hoi. ((hieu viec) OR (sieu viet)) cac luc va hanh vai cua te*".
