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