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