• Performing a fuzzy search may retrieve terms with similar spellings: vu ((bac ky) OR (sac ky)) tang xa hoi. hieu ((van cam) or (van nam)) xuc va tinh va cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((bac ky) OR (sac ky)) tang xa hoi. hieu ((van cam) OR (van nam)) xuc va tinh va cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((bac ky) OR (sac ky)) tang xa hoi. hieu ((van cam) or (van nam)) xuc va tinh va cua tre".
• Adding a wildcard symbol may retrieve word variants: vu ((bac ky) OR (sac ky)) tang xa hoi. hieu ((van cam) or (van nam)) xuc va tinh va cua tre*.
