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