• Performing a fuzzy search may retrieve terms with similar spellings: ((toc sach) OR (thuoc sach)) cam nang xa hoi. hieu ((ve cham) or (va cham)) soc va danh dien cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc sach) OR (thuoc sach)) cam nang xa hoi. hieu ((ve cham) OR (va cham)) soc va danh dien cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc sach) OR (thuoc sach)) cam nang xa hoi. hieu ((ve cham) or (va cham)) soc va danh dien cua tu".
• Adding a wildcard symbol may retrieve word variants: ((toc sach) OR (thuoc sach)) cam nang xa hoi. hieu ((ve cham) or (va cham)) soc va danh dien cua tu*.
