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 pham duc snippets" » "dung phan duc snippets", "hung pham duc snippets", "tung pham duc snippets"
"locating bug core snippets" » "locating bug code snippets"

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

• Removing quotes may allow a broader search: (((( using data code snippets ) or ( dung pham duc snippets ))) or ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using data code snippets") or ("dung pham duc snippets"))) or ("locating bug core snippets"))*.
