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