• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang ((o hai) or (co hai)). hieu ve chat xuc van ((khanh thai) OR (khanh thuan)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang ((o hai) OR (co hai)). hieu ve chat xuc van ((khanh thai) OR (khanh thuan)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang ((o hai) or (co hai)). hieu ve chat xuc van ((khanh thai) OR (khanh thuan)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang ((o hai) or (co hai)). hieu ve chat xuc van ((khanh thai) OR (khanh thuan)) cuu tre*.
