• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty nang x hoi. hieu va cac xuc ban hanh lam ((cho tre) or (((ca tren) OR (la tren))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang x hoi. hieu va cac xuc ban hanh lam ((cho tre) OR (((ca tren) OR (la tren)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang x hoi. hieu va cac xuc ban hanh lam ((cho tre) or (((ca tren) OR (la tren))))".
• Adding a wildcard symbol may retrieve word variants: su sach ty nang x hoi. hieu va cac xuc ban hanh lam ((cho tre) or (((ca tren) OR (la tren))))*.
