• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ((ky tang) OR (ky dang)) lai hoi. hieu su chat ((xuc va) or (duc va)) hanh hai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ((ky tang) OR (ky dang)) lai hoi. hieu su chat ((xuc va) OR (duc va)) hanh hai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ((ky tang) OR (ky dang)) lai hoi. hieu su chat ((xuc va) or (duc va)) hanh hai cua te".
• Adding a wildcard symbol may retrieve word variants: tu sac ((ky tang) OR (ky dang)) lai hoi. hieu su chat ((xuc va) or (duc va)) hanh hai cua te*.
