• Performing a fuzzy search may retrieve terms with similar spellings: thu san kho tang xa hoi. hieu van ((cau luc) OR (cau phuc)) va hanh de ((cau tre) or (cau tra))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu san kho tang xa hoi. hieu van ((cau luc) OR (cau phuc)) va hanh de ((cau tre) OR (cau tra)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu san kho tang xa hoi. hieu van ((cau luc) OR (cau phuc)) va hanh de ((cau tre) or (cau tra))".
• Adding a wildcard symbol may retrieve word variants: thu san kho tang xa hoi. hieu van ((cau luc) OR (cau phuc)) va hanh de ((cau tre) or (cau tra))*.
