• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty ((((xang ma) OR (rang ma))) or (sang ma)) hoi. hieu ve cham duc va hanh tai chau triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty ((((xang ma) OR (rang ma))) OR (sang ma)) hoi. hieu ve cham duc va hanh tai chau triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty ((((xang ma) OR (rang ma))) or (sang ma)) hoi. hieu ve cham duc va hanh tai chau triet".
• Adding a wildcard symbol may retrieve word variants: thu sach ty ((((xang ma) OR (rang ma))) or (sang ma)) hoi. hieu ve cham duc va hanh tai chau triet*.
