Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"vu dinh vat snippets" » "vu sinh vat snippets", "vu dinh van snippets", "vu dinh dat snippets", "quy dinh vat snippets", "vu dinh vat slippers"
"using a java snippets" » "using _ java snippets", "using a java slippers"

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: "((((\"vu dinh vat snippets\") OR (\"using a java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( vu dinh vat snippets ) OR ( using a java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vu dinh vat snippets") OR ("using a java snippets"))) OR ("locating bugs code snippets"))*.
