• Performing a fuzzy search may retrieve terms with similar spellings: (("pho gian van tien thu") or ((((("pho cap qua tiep cua") OR ("pho cay qua tiep cua"))) or ((("pho sach luan dieu cua") or ("pho sach luan dieu tra"))))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("pho gian van tien thu") OR ((((("pho cap qua tiep cua") OR ("pho cay qua tiep cua"))) OR ((("pho sach luan dieu cua") OR ("pho sach luan dieu tra"))))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"pho gian van tien thu\") or (((((\"pho cap qua tiep cua\") OR (\"pho cay qua tiep cua\"))) or (((\"pho sach luan dieu cua\") or (\"pho sach luan dieu tra\"))))))*".
• Removing quotes may allow a broader search: (( pho gian van tien thu ) or ((((( pho cap qua tiep cua ) OR ( pho cay qua tiep cua ))) or ((( pho sach luan dieu cua ) or ( pho sach luan dieu tra ))))))*.
