• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ky) OR (sac ky)) ((nang xa) or (lang xa)) hoi. hieu van cao duc va han tai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sac ky)) ((nang xa) OR (lang xa)) hoi. hieu van cao duc va han tai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sac ky)) ((nang xa) or (lang xa)) hoi. hieu van cao duc va han tai cua te".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sac ky)) ((nang xa) or (lang xa)) hoi. hieu van cao duc va han tai cua te*.
