Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"mot cao dan snippets" » "mot co dan snippets", "mot cai dan snippets", "mot cay dan snippets", "mot cao dang snippets", "mot cao danh snippets", "mot cac dan snippets", "mot cao dan 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: "((((\"mot cao dan snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( mot cao dan snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("mot cao dan snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
