• Performing a fuzzy search may retrieve terms with similar spellings: toc sac ky danh xa hoi. hieu ve cac tu va doanh ((((mang cua) OR (dung cua))) or (tang cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sac ky danh xa hoi. hieu ve cac tu va doanh ((((mang cua) OR (dung cua))) OR (tang cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sac ky danh xa hoi. hieu ve cac tu va doanh ((((mang cua) OR (dung cua))) or (tang cua)) tre*".
