Perhaps you should try some spelling variations:
"dung sai va snippets" » "dung tai va snippets", "dung va va snippets", "dung dat va snippets", "dung mai va snippets", "dung dai va snippets", "dung hai va snippets", "dung sai va slippers"
"using _ java snippets" » "using _ java slippers"
"locating bug code snippets" » "locating bug code slippers", "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: "((((\"dung sai va snippets\") OR (\"using _ java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dung sai va snippets ) OR ( using _ java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung sai va snippets") OR ("using _ java snippets"))) OR ("locating bug code snippets"))*.
