Perhaps you should try some spelling variations:
"python using data slippery" » "python using java slippery", "python using sat slippery", "python missing data slippery", "python using data slippers"
"dau tu ban snippets" » "dau thu ban snippets", "dau te ban snippets", "dau tu ban 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: "((((\"dau tu ban snippets\") OR (\"python using data slippery\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dau tu ban snippets ) OR ( python using data slippery ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dau tu ban snippets") OR ("python using data slippery"))) OR ("locating bug code snippets"))*.
