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