Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"vung dat chi snippets" » "dung dat chi snippets", "vung va chi snippets", "vung dat cho snippets", "vung dat thi snippets", "vung dau chi 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 (\"vung dat chi snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( vung dat chi snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("vung dat chi snippets"))) OR ("locating bugs code snippets"))*.
