• Performing a fuzzy search may retrieve terms with similar spellings: vu ban ky nang ma hoi. hieu viec cua ((luc va) OR (duc va)) hanh ((va cua) or (via cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ban ky nang ma hoi. hieu viec cua ((luc va) OR (duc va)) hanh ((va cua) OR (via cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ban ky nang ma hoi. hieu viec cua ((luc va) OR (duc va)) hanh ((va cua) or (via cua)) te*".
