Perhaps you should try some spelling variations:
"using java java snippets" » "using data java snippets"
"tin duong van slippers" » "tin dung van slippers", "tim duong van slippers", "tin huong van slippers", "tin duong va slippers", "tin luong va slippers", "tin dang van slippers", "tin duong van slippery", "tin duong van 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 (\"tin duong van slippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java java snippets ) OR ( tin duong van slippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java java snippets") OR ("tin duong van slippers"))) OR ("locating bug code snippets"))*.
