Perhaps you should try some spelling variations:
"dung java java snippets" » "dung va java snippets"
"tranh cua core snippets" » "doanh cua core snippets", "manh cua core snippets", "tranh cua cong snippets", "tranh cua co snippets", "tranh cua che snippets"
"locating bug code 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: "((((\"dung java java snippets\") OR (\"tranh cua core snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dung java java snippets ) OR ( tranh cua core snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung java java snippets") OR ("tranh cua core snippets"))) OR ("locating bug code snippets"))*.
