• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky nang cac khoi. hieu vu cham cuc ban hanh ((((vi cua) OR (vai cua))) or (di cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang cac khoi. hieu vu cham cuc ban hanh ((((vi cua) OR (vai cua))) OR (di cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang cac khoi. hieu vu cham cuc ban hanh ((((vi cua) OR (vai cua))) or (di cua)) tre*".
