• Performing a fuzzy search may retrieve terms with similar spellings: ((te san) OR (ke san)) ky nang xa hoi. hieu ((va cham) or (va chat)) luc va hanh tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te san) OR (ke san)) ky nang xa hoi. hieu ((va cham) OR (va chat)) luc va hanh tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te san) OR (ke san)) ky nang xa hoi. hieu ((va cham) or (va chat)) luc va hanh tai cua tre".
• Adding a wildcard symbol may retrieve word variants: ((te san) OR (ke san)) ky nang xa hoi. hieu ((va cham) or (va chat)) luc va hanh tai cua tre*.
