• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"trinh tran hung snippets\") OR (\"dung bug code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( trinh tran hung snippets ) OR ( dung bug code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trinh tran hung snippets") OR ("dung bug code snippets"))) OR ("locating bug code snippets"))*.
