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 trung do snippets" » "dung trong do snippets", "quang trung do snippets", "truong trung do snippets", "dung trung bo snippets", "dung trung co snippets", "dung trung du snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code 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 trung do snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using data code snippets ) OR ( dung trung do snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using data code snippets") OR ("dung trung do snippets"))) OR ("locating bug code snippets"))*.
