• Performing a fuzzy search may retrieve terms with similar spellings: toc ((sach ly) OR (sach ty)) nang xa hoi. hieu vien cam xuc ((van ha) or (van hoa)) noi cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach ly) OR (sach ty)) nang xa hoi. hieu vien cam xuc ((van ha) OR (van hoa)) noi cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ly) OR (sach ty)) nang xa hoi. hieu vien cam xuc ((van ha) or (van hoa)) noi cua tu".
• Adding a wildcard symbol may retrieve word variants: toc ((sach ly) OR (sach ty)) nang xa hoi. hieu vien cam xuc ((van ha) or (van hoa)) noi cua tu*.
