• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky mang dat hoi. hieu doc ((chat xuc) OR (chat huu)) va hanh ((tai cua) OR (thai cua)) te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky mang dat hoi. hieu doc ((chat xuc) OR (chat huu)) va hanh ((tai cua) or (thai cua)) te~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky mang dat hoi. hieu doc ((chat xuc) OR (chat huu)) va hanh ((tai cua) or (thai cua)) te*.
