• Performing a fuzzy search may retrieve terms with similar spellings: thuat san ky nang xa hoi. hieu ((((van cac) OR (van hac))) or (van bac)) nuoc va nang thai cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat san ky nang xa hoi. hieu ((((van cac) OR (van hac))) OR (van bac)) nuoc va nang thai cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat san ky nang xa hoi. hieu ((((van cac) OR (van hac))) or (van bac)) nuoc va nang thai cua tu".
• Adding a wildcard symbol may retrieve word variants: thuat san ky nang xa hoi. hieu ((((van cac) OR (van hac))) or (van bac)) nuoc va nang thai cua tu*.
