Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets", "using java core snippets"
"dung nam cho snippets" » "dong nam cho snippets", "dung lam cho snippets", "sung nam cho snippets", "dung nam chon snippets", "dung nam chi snippets", "dung nam cao snippets"
"locating bug code snippets" » "locating bug core 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 java code snippets\") OR (\"dung nam cho snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( dung nam cho snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("dung nam cho snippets"))) OR ("locating bug code snippets"))*.
