• Performing a fuzzy search may retrieve terms with similar spellings: (((("quan de xa hoi.") OR ("luan de xa hoi."))) OR ("quan den xa hoi."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"quan de xa hoi.\") OR (\"luan de xa hoi.\"))) OR (\"quan den xa hoi.\"))".
• Removing quotes may allow a broader search: (((( quan de xa hoi. ) OR ( luan de xa hoi. ))) OR ( quan den xa hoi. )).
• Adding a wildcard symbol may retrieve word variants: (((("quan de xa hoi.") OR ("luan de xa hoi."))) OR ("quan den xa hoi."))*.
