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