Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"using java java snippets" » "using data java snippets"
"danh cau java snippets" » "danh dau java snippets", "danh ca java snippets", "danh hau java snippets", "danh cau va snippets", "danh ngu java 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: "((((\"danh cau java snippets\") OR (\"using java java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( danh cau java snippets ) OR ( using java java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("danh cau java snippets") OR ("using java java snippets"))) OR ("locating bug core snippets"))*.
