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 co cong snippets" » "dung cho cong snippets", "dung cong cong snippets", "dung cua cong snippets", "dung cao cong snippets", "dung bo cong 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 co cong snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using data code snippets ) OR ( dung co cong snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using data code snippets") OR ("dung co cong snippets"))) OR ("locating bugs code snippets"))*.
