• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ky nang xa hoi. thien van ((bac tuc) OR (bac thua)) va thanh vi ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky nang xa hoi. thien van ((bac tuc) OR (bac thua)) va thanh vi ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky nang xa hoi. thien van ((bac tuc) OR (bac thua)) va thanh vi ((cua tre) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: vu sach ky nang xa hoi. thien van ((bac tuc) OR (bac thua)) va thanh vi ((cua tre) or (cuu tre))*.
