Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets"
"dung ung ho snippets" » "dung trung ho snippets", "dung quang ho snippets", "dung chung ho snippets", "dung tung ho snippets", "dung ung hoa snippets", "dung ung pho 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 ung ho snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( dung ung ho snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("dung ung ho snippets"))) OR ("locating bug core snippets"))*.
