• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky tang lai hoi. hieu su ((chao tu) OR (choi tu)) va hanh ((vi cua) OR (vai cua)) te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky tang lai hoi. hieu su ((chao tu) or (choi tu)) va hanh ((vi cua) OR (vai cua)) te~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky tang lai hoi. hieu su ((chao tu) or (choi tu)) va hanh ((vi cua) OR (vai cua)) te*.
