Perhaps you should try some spelling variations:
"using java java snippets" » "using data java snippets"
"voi trong dan slippers" » "doi trong dan slippers", "hoi trong dan slippers", "vai trong dan slippers", "voi trong dang slippers", "voi trong san slippers", "voi trong tan slippers", "voi trong dan slippery", "voi trong dan 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: "((((\"using java java snippets\") OR (\"voi trong dan slippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java java snippets ) OR ( voi trong dan slippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java java snippets") OR ("voi trong dan slippers"))) OR ("locating bug code snippets"))*.
