Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets"
"dung tri phi snippets" » "dung tai phi snippets", "dung tren phi snippets", "nhung tri phi snippets", "dung thi phi snippets", "dung tri phu snippets", "dung tri chi 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 tri phi snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( dung tri phi snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("dung tri phi snippets"))) OR ("locating bug core snippets"))*.
