Perhaps you should try some spelling variations:
"vi dinh vat snippets" » "vi sinh vat snippets", "vi dinh van snippets", "vi dinh dat snippets", "vi tinh vat snippets", "vu dinh vat snippets", "vi dinh vat slippers"
"using a java snippets" » "using _ java snippets", "using a 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: "((((\"vi dinh vat snippets\") OR (\"using a java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( vi dinh vat snippets ) OR ( using a java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vi dinh vat snippets") OR ("using a java snippets"))) OR ("locating bug code snippets"))*.
