Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"hung tran he snippets" » "huong tran he snippets", "quang tran he snippets", "hung thang he snippets", "hung toan he snippets", "hung tran hien snippets", "hung tran hiep 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 java code snippets\") OR (\"hung tran he snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( hung tran he snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("hung tran he snippets"))) OR ("locating bugs code snippets"))*.
