Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"yong wang do snippets" » "ying wang do snippets", "cong wang do snippets", "yong fang do snippets", "yong dang do snippets", "yong tang do snippets", "yong wang dong 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 code snippets\") OR (\"yong wang do snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( yong wang do snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("yong wang do snippets"))) OR ("locating bugs code snippets"))*.
