• Performing a fuzzy search may retrieve terms with similar spellings: tu san ky nang lai hoi. hieu ((vu chat) OR (va chat)) xuc va thanh ((ve cua) or (de cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky nang lai hoi. hieu ((vu chat) OR (va chat)) xuc va thanh ((ve cua) OR (de cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky nang lai hoi. hieu ((vu chat) OR (va chat)) xuc va thanh ((ve cua) or (de cua)) te".
• Adding a wildcard symbol may retrieve word variants: tu san ky nang lai hoi. hieu ((vu chat) OR (va chat)) xuc va thanh ((ve cua) or (de cua)) te*.
