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