• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty hang xa hoi. hieu vu ((cham luu) or (((phap luu) OR (phap lua)))) van anh vi su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty hang xa hoi. hieu vu ((cham luu) OR (((phap luu) OR (phap lua)))) van anh vi su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty hang xa hoi. hieu vu ((cham luu) or (((phap luu) OR (phap lua)))) van anh vi su triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ty hang xa hoi. hieu vu ((cham luu) or (((phap luu) OR (phap lua)))) van anh vi su triet*.
