• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty nang xa hoi. lieu va lam ((xuc va) OR (tuc va)) lanh ((hai cua) or (hoi cua)) su~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang xa hoi. lieu va lam ((xuc va) OR (tuc va)) lanh ((hai cua) OR (hoi cua)) su.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang xa hoi. lieu va lam ((xuc va) OR (tuc va)) lanh ((hai cua) or (hoi cua)) su".
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang xa hoi. lieu va lam ((xuc va) OR (tuc va)) lanh ((hai cua) or (hoi cua)) su*.
