Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"dung trinh java snippets" » "dung tinh java snippets", "dong trinh java snippets", "cong trinh java snippets"
"using c core snippets" » "using lc core snippets", "using a core snippets", "using _ core 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 c core snippets\") OR (\"dung trinh java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using c core snippets ) OR ( dung trinh java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using c core snippets") OR ("dung trinh java snippets"))) OR ("locating bugs code snippets"))*.
