Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"using java code snippets" » "using data code snippets", "using java code slippers"
"dung ha lan snippets" » "dung va lan snippets", "dung he lan snippets", "dung khoa lan snippets", "dung ha lang snippets", "dung hai lan snippets", "dung hoa lan snippets", "dung ha lan slippers"

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 (\"dung ha lan snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( dung ha lan snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("dung ha lan snippets"))) OR ("locating bugs code snippets"))*.
