• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty nang xa hoi. lieu ((va chat) OR (van chat)) duc minh ((hang van) or (hang va)) va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty nang xa hoi. lieu ((va chat) OR (van chat)) duc minh ((hang van) OR (hang va)) va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty nang xa hoi. lieu ((va chat) OR (van chat)) duc minh ((hang van) or (hang va)) va triet".
• Adding a wildcard symbol may retrieve word variants: thu sach ty nang xa hoi. lieu ((va chat) OR (van chat)) duc minh ((hang van) or (hang va)) va triet*.
