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