• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((((ky tang) OR (ky trong))) or (ky nang)) ma hoi. hieu ve cham loc va hanh le cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((((ky tang) OR (ky trong))) OR (ky nang)) ma hoi. hieu ve cham loc va hanh le cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((((ky tang) OR (ky trong))) or (ky nang)) ma hoi. hieu ve cham loc va hanh le cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((((ky tang) OR (ky trong))) or (ky nang)) ma hoi. hieu ve cham loc va hanh le cua tre*.
