• Performing a fuzzy search may retrieve terms with similar spellings: tu cach hoc tap, nhiem cuu mot ((goc nganh) or (hoc nganh)) khong thuoc la hoi van von tai~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cach hoc tap, nhiem cuu mot ((goc nganh) OR (hoc nganh)) khong thuoc la hoi van von tai.
• Adding a wildcard symbol may retrieve word variants: tu cach hoc tap, nhiem cuu mot ((goc nganh) or (hoc nganh)) khong thuoc la hoi van von tai*.
