• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky nang xa hoi. hieu ca ((chat truc) or (chat xuc)) ((va dan) OR (va dao)) dai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky nang xa hoi. hieu ca ((chat truc) OR (chat xuc)) ((va dan) OR (va dao)) dai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky nang xa hoi. hieu ca ((chat truc) or (chat xuc)) ((va dan) OR (va dao)) dai cua tre".
• Adding a wildcard symbol may retrieve word variants: thu sach ky nang xa hoi. hieu ca ((chat truc) or (chat xuc)) ((va dan) OR (va dao)) dai cua tre*.
