• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ty hang ca hoi. hieu va cam ((xuc va) OR (tuc va)) ((hanh vai) OR (hanh va)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ty hang ca hoi. hieu va cam ((xuc va) or (tuc va)) ((hanh vai) OR (hanh va)) cua te".
• Adding a wildcard symbol may retrieve word variants: thuat sach ty hang ca hoi. hieu va cam ((xuc va) or (tuc va)) ((hanh vai) OR (hanh va)) cua te*.
