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