Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"using java java snippets" » "using data java snippets"
"rang dong va snippets" » "nang dong va snippets", "lang dong va snippets", "wang dong va snippets", "rang dung va snippets", "rang dong ha snippets", "rang luong va 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 (\"rang dong va snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using java java snippets ) OR ( rang dong va snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java java snippets") OR ("rang dong va snippets"))) OR ("locating bug core snippets"))*.
