Perhaps you should try some spelling variations:
"using java java snippets" » "using data java snippets"
"quy sinh vat slippers" » "quy dinh vat slippers", "huy sinh vat slippers", "quy ninh vat slippers", "quy sinh vat slippery", "quy sinh vat grippers"
"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: "((((\"quy sinh vat slippers\") OR (\"using java java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( quy sinh vat slippers ) OR ( using java java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("quy sinh vat slippers") OR ("using java java snippets"))) OR ("locating bug code snippets"))*.
