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