Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets"
"locating bug core snippets" » "locating bug code snippets"
"dung cu danh snippets" » "dung cua danh snippets", "dung co danh snippets", "dung cho danh snippets", "dung cum danh snippets", "dung cau danh snippets", "dung cuu danh 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 cu danh snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( dung cu danh snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("dung cu danh snippets"))) OR ("locating bug core snippets"))*.
