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"
"hoc dan mo snippets" » "hoc dan mon snippets", "hoc dan so snippets", "hoc fan mo 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: "((((\"hoc dan mo snippets\") OR (\"python using data slippery\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( hoc dan mo snippets ) OR ( python using data slippery ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hoc dan mo snippets") OR ("python using data slippery"))) OR ("locating bug code snippets"))*.
