• If you are trying to use Boolean operators, they must be ALL CAPS: te cac ky tang hoa hoi. hieu ((qua cac) OR (qua than)) soc ban thanh ((vi cua) OR (vai cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cac ky tang hoa hoi. hieu ((qua cac) or (qua than)) soc ban thanh ((vi cua) OR (vai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: te cac ky tang hoa hoi. hieu ((qua cac) or (qua than)) soc ban thanh ((vi cua) OR (vai cua)) tre*.
