• Performing a fuzzy search may retrieve terms with similar spellings: su ((dai ky) OR (dai ly)) lang xa hoi. hieu van cac xuc va hanh ((hai cua) or (thai cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((dai ky) OR (dai ly)) lang xa hoi. hieu van cac xuc va hanh ((hai cua) OR (thai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((dai ky) OR (dai ly)) lang xa hoi. hieu van cac xuc va hanh ((hai cua) or (thai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: su ((dai ky) OR (dai ly)) lang xa hoi. hieu van cac xuc va hanh ((hai cua) or (thai cua)) tre*.
