• Performing a fuzzy search may retrieve terms with similar spellings: te sac ((ky trang) OR (ke trang)) xa hoi. hieu van chat soc van anh ((vi cuu) or (dinh cuu)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ((ky trang) OR (ke trang)) xa hoi. hieu van chat soc van anh ((vi cuu) OR (dinh cuu)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ((ky trang) OR (ke trang)) xa hoi. hieu van chat soc van anh ((vi cuu) or (dinh cuu)) tre*".
