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