Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets"
"dung cung dat snippets" » "dung chung dat snippets", "dung cong dat snippets", "dung ung dat snippets", "dung dung dat snippets", "dung vung dat snippets", "dung cuong dao 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 cung dat snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( dung cung dat snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("dung cung dat snippets"))) OR ("locating bug core snippets"))*.
