Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"dan dung doi snippets" » "van dung doi snippets", "tin dung doi snippets", "ap dung doi snippets", "dan huong doi snippets", "dan dung tai snippets", "dan dung co 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 (\"dan dung doi snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( dan dung doi snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("dan dung doi snippets"))) OR ("locating bugs code snippets"))*.
