• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty xang xa hoi. thien van nam cua vat thanh vi ((((cua tre) or (cua triet))) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty xang xa hoi. thien van nam cua vat thanh vi ((((cua tre) OR (cua triet))) OR (cua te)).
• Adding a wildcard symbol may retrieve word variants: tu sach ty xang xa hoi. thien van nam cua vat thanh vi ((((cua tre) or (cua triet))) or (cua te))*.
