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