• Performing a fuzzy search may retrieve terms with similar spellings: ((so sach) or (((so sanh) OR (do sanh)))) y nang xa hoi. hieu va cac thu va thanh ve cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (((so sanh) OR (do sanh)))) y nang xa hoi. hieu va cac thu va thanh ve cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) or (((so sanh) OR (do sanh)))) y nang xa hoi. hieu va cac thu va thanh ve cua tu".
• Adding a wildcard symbol may retrieve word variants: ((so sach) or (((so sanh) OR (do sanh)))) y nang xa hoi. hieu va cac thu va thanh ve cua tu*.
