• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thu ((dang xay) or (lang xa)) hoi. hieu van cam luc ban hanh ((di cua) OR (doi cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu ((dang xay) OR (lang xa)) hoi. hieu van cam luc ban hanh ((di cua) OR (doi cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu ((dang xay) or (lang xa)) hoi. hieu van cam luc ban hanh ((di cua) OR (doi cua)) te*".
