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