• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thu xang xa hoi. hieu ((tu cham) or (vu kham)) hoc vat hanh ((vai cua) OR (dai cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu xang xa hoi. hieu ((tu cham) OR (vu kham)) hoc vat hanh ((vai cua) OR (dai cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu xang xa hoi. hieu ((tu cham) or (vu kham)) hoc vat hanh ((vai cua) OR (dai cua)) te".
• Adding a wildcard symbol may retrieve word variants: tu sach thu xang xa hoi. hieu ((tu cham) or (vu kham)) hoc vat hanh ((vai cua) OR (dai cua)) te*.
