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 luan he snippets" » "dung luan che snippets", "dung quan he snippets", "dung luan ve 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 luan he snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using data code snippets ) OR ( dung luan he snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using data code snippets") OR ("dung luan he snippets"))) OR ("locating bugs code snippets"))*.
