Perhaps you should try some spelling variations:
"using java java snippets" » "using data java snippets", "using java java slippers"
"va tinh bac slippery" » "va tinh cach slippery", "va tinh hoc slippery", "va tinh lao slippery", "may tinh bac slippery", "va tinh bac slippers"
"locating bug code snippets" » "locating bug code slippers", "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: "((((\"va tinh bac slippery\") OR (\"using java java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( va tinh bac slippery ) OR ( using java java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("va tinh bac slippery") OR ("using java java snippets"))) OR ("locating bug code snippets"))*.
