• Performing a fuzzy search may retrieve terms with similar spellings: te sach thue nang xa hoi. hieu ((van chat) or (phan dau)) xuc va hanh ((vi cuu) OR (vinh cuu)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thue nang xa hoi. hieu ((van chat) OR (phan dau)) xuc va hanh ((vi cuu) OR (vinh cuu)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thue nang xa hoi. hieu ((van chat) or (phan dau)) xuc va hanh ((vi cuu) OR (vinh cuu)) tre".
• Adding a wildcard symbol may retrieve word variants: te sach thue nang xa hoi. hieu ((van chat) or (phan dau)) xuc va hanh ((vi cuu) OR (vinh cuu)) tre*.
