Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using data code snippets" » "using java code snippets", "using sat code snippets", "missing data code snippets", "using rate code snippets"
"dung con cua snippets" » "dung cong cua snippets", "dung von cua snippets", "dung co cua snippets", "dung dong cua 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 con cua snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using data code snippets ) OR ( dung con cua snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using data code snippets") OR ("dung con cua snippets"))) OR ("locating bugs code snippets"))*.
