Perhaps you should try some spelling variations:
"using java can snippets" » "using data can snippets"
"anh trinh java snippets" » "hanh trinh java snippets", "anh tinh java snippets", "thanh trinh java snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug core 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: "((((\"anh trinh java snippets\") OR (\"using java can snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( anh trinh java snippets ) OR ( using java can snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("anh trinh java snippets") OR ("using java can snippets"))) OR ("locating bug code snippets"))*.
