• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ((ky sang) OR (ky dang)) ma hoi. hieu ((van cau) or (van nam)) xuc ban thanh va chua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ((ky sang) OR (ky dang)) ma hoi. hieu ((van cau) OR (van nam)) xuc ban thanh va chua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ((ky sang) OR (ky dang)) ma hoi. hieu ((van cau) or (van nam)) xuc ban thanh va chua tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ((ky sang) OR (ky dang)) ma hoi. hieu ((van cau) or (van nam)) xuc ban thanh va chua tre*.
