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