Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java java snippets" » "using data java snippets"
"nam trung co snippets" » "nam trong co snippets", "tai trung co snippets", "ba trung co snippets", "nam trung bo snippets", "nam truong cao 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 java snippets\") OR (\"nam trung co snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java java snippets ) OR ( nam trung co snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java java snippets") OR ("nam trung co snippets"))) OR ("locating bugs code snippets"))*.
