• Performing a fuzzy search may retrieve terms with similar spellings: toc ((sach ky) OR (sach y)) nang xa hoi. thi van ((cau truc) or (chu duc)) manh nhan tai cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach ky) OR (sach y)) nang xa hoi. thi van ((cau truc) OR (chu duc)) manh nhan tai cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ky) OR (sach y)) nang xa hoi. thi van ((cau truc) or (chu duc)) manh nhan tai cua tu".
• Adding a wildcard symbol may retrieve word variants: toc ((sach ky) OR (sach y)) nang xa hoi. thi van ((cau truc) or (chu duc)) manh nhan tai cua tu*.
