Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java core snippets" » "using data core snippets"
"dung tu phap snippets" » "dung thu phap snippets", "dung tru phap snippets", "dung cu phap snippets", "dung tu phat snippets", "dung ngu phap 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 core snippets\") OR (\"dung tu phap snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java core snippets ) OR ( dung tu phap snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java core snippets") OR ("dung tu phap snippets"))) OR ("locating bugs code snippets"))*.
