• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang xa hoi. thien van cau duc van ((phan tai) or (phan thi)) ((cua tu) OR (cua tuc))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. thien van cau duc van ((phan tai) OR (phan thi)) ((cua tu) OR (cua tuc)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. thien van cau duc van ((phan tai) or (phan thi)) ((cua tu) OR (cua tuc))".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang xa hoi. thien van cau duc van ((phan tai) or (phan thi)) ((cua tu) OR (cua tuc))*.
