• Performing a fuzzy search may retrieve terms with similar spellings: vu ((ban ky) or (dan ky)) nang ma hoi. hieu van ((cam luc) or (cau luc)) va nang giau cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((ban ky) OR (dan ky)) nang ma hoi. hieu van ((cam luc) OR (cau luc)) va nang giau cua tre.
• Adding a wildcard symbol may retrieve word variants: vu ((ban ky) or (dan ky)) nang ma hoi. hieu van ((cam luc) or (cau luc)) va nang giau cua tre*.
