Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"dung qua du snippets" » "dung qua code snippets", "duong qua du snippets", "dung quan du snippets", "dung cua du snippets", "dung qua dau snippets", "dung qua su snippets", "dung qua cu snippets"
"python using java snippets" » "python using data 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: "((((\"python using java snippets\") OR (\"dung qua du snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( dung qua du snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("dung qua du snippets"))) OR ("locating bug core snippets"))*.
