Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java java snippets" » "using data java snippets"
"vi tran van slippers" » "vi luan van slippers", "vi trang van slippers", "v tran van slippers", "vi than van slippers", "vi tran van slippery", "vi tran van grippers"

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