• Performing a fuzzy search may retrieve terms with similar spellings: nuoc san ky nang x hoi. hieu ky ((cau phuc) or (huu phuc)) vu ((hanh te) OR (hanh ve)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: nuoc san ky nang x hoi. hieu ky ((cau phuc) OR (huu phuc)) vu ((hanh te) OR (hanh ve)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc san ky nang x hoi. hieu ky ((cau phuc) or (huu phuc)) vu ((hanh te) OR (hanh ve)) cua tre*".
