Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets"
"dung dan ba snippets" » "dung dat ba snippets", "dung san ba snippets", "tung dan ba snippets", "dung dan bac snippets", "dung dan ca snippets", "dung dan va snippets"
"locating bug core snippets" » "locating bug code 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 (\"dung dan ba snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( dung dan ba snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("dung dan ba snippets"))) OR ("locating bug core snippets"))*.
