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