Perhaps you should try some spelling variations:
"python using real slippers" » "python using metal slippers", "python using raw slippers", "python using real slippery", "python using real grippers"
"tham do 3 snippets" » "thai do 3 snippets", "pham do 3 snippets", "tham du 3 snippets", "tham doc 3 snippets", "tham doi 3 snippets", "tham do _ 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 using real slippers\") OR (\"tham do 3 snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using real slippers ) OR ( tham do 3 snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using real slippers") OR ("tham do 3 snippets"))) OR ("locating bug code snippets"))*.
