Perhaps you should try some spelling variations:
"python missing data slippers" » "python using data slippers", "python missing data slippery", "python missing data grippers"
"thay do 4 snippets" » "thay doi 4 snippets", "thai do 4 snippets", "thuy do 4 snippets", "thay doc 4 snippets", "thay do _ snippets", "thay do 5 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: "((((\"python missing data slippers\") OR (\"thay do 4 snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python missing data slippers ) OR ( thay do 4 snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python missing data slippers") OR ("thay do 4 snippets"))) OR ("locating bug code snippets"))*.
