• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ty) OR (sach tu)) xang xa hoi. hieu van cac xuc ban dinh ((vi cua) or (doi cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ty) OR (sach tu)) xang xa hoi. hieu van cac xuc ban dinh ((vi cua) OR (doi cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ty) OR (sach tu)) xang xa hoi. hieu van cac xuc ban dinh ((vi cua) or (doi cua)) te*".
