• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((sach ky) OR (sach ty)) nang ma hoi. hieu ((ve cham) or (vu cham)) xuc va thanh san cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((sach ky) OR (sach ty)) nang ma hoi. hieu ((ve cham) OR (vu cham)) xuc va thanh san cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((sach ky) OR (sach ty)) nang ma hoi. hieu ((ve cham) or (vu cham)) xuc va thanh san cau treo".
• Adding a wildcard symbol may retrieve word variants: hoc ((sach ky) OR (sach ty)) nang ma hoi. hieu ((ve cham) or (vu cham)) xuc va thanh san cau treo*.
