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