Perhaps you should try some spelling variations:
"hanh java java snippets" » "hanh va java snippets"
"dung anh cong snippets" » "dung danh cong snippets", "duong anh cong snippets", "dong anh cong snippets", "dung hanh cong snippets", "dung anh dong snippets", "dung thanh cong 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: "((((\"hanh java java snippets\") OR (\"dung anh cong snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( hanh java java snippets ) OR ( dung anh cong snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hanh java java snippets") OR ("dung anh cong snippets"))) OR ("locating bug code snippets"))*.
