Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets", "using java core snippets"
"han danh chi snippets" » "van danh chi snippets", "phan dang chi snippets", "nhan dang chi snippets", "han danh cho snippets", "han dinh chi snippets", "han banh chi snippets"
"locating bug code snippets" » "locating bug core snippets", "locating bung code snippets", "locating bugs 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 (\"han danh chi snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( han danh chi snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("han danh chi snippets"))) OR ("locating bug code snippets"))*.
