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"
"thuc dap so snippets" » "thuc dan so snippets", "thuc day so snippets", "thuc tap so snippets", "thuc dai so snippets"
"locating bug code snippets" » "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: "((((\"thuc dap so snippets\") OR (\"python using data slippery\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( thuc dap so snippets ) OR ( python using data slippery ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thuc dap so snippets") OR ("python using data slippery"))) OR ("locating bug code snippets"))*.
