Perhaps you should try some spelling variations:
"using java java snippets" » "using data java snippets", "using java java slippers"
"thanh hai va snippets" » "thanh phan va snippets", "thanh hoa va snippets", "thanh san va snippets", "thanh hai van snippets", "thanh thai va snippets", "thanh hoi va snippets", "thanh hai va 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: "((((\"thanh hai va snippets\") OR (\"using java java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( thanh hai va snippets ) OR ( using java java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thanh hai va snippets") OR ("using java java snippets"))) OR ("locating bug code snippets"))*.
