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