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