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"
"ly ve trong snippets" » "ly le trong snippets", "ly ke trong snippets", "ly ve tuong snippets", "ly va trong 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: "((((\"ly ve trong snippets\") OR (\"python using real slippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( ly ve trong snippets ) OR ( python using real slippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("ly ve trong snippets") OR ("python using real slippers"))) OR ("locating bug code snippets"))*.
