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