Perhaps you should try some spelling variations:
"using java java slippers" » "using data java slippers", "using java java slippery", "using java java grippers"
"vi sinh code snippets" » "vi sinh cong snippets", "vi sinh de snippets", "vi sinh co snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code 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: "((((\"vi sinh code snippets\") OR (\"using java java slippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( vi sinh code snippets ) OR ( using java java slippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vi sinh code snippets") OR ("using java java slippers"))) OR ("locating bug code snippets"))*.
