Perhaps you should try some spelling variations:
"using data code snippets" » "using java code snippets", "using sat code snippets", "missing data code snippets", "using rate code snippets"
"dung hoc can snippets" » "dong hoc can snippets", "dung thuoc can snippets", "trung hoc can snippets", "dung hoc dan snippets", "dung hoc cao snippets", "dung hoc cac snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets"

You may be able to get more results by adjusting your search query.

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