Perhaps you should try some spelling variations:
"python using raw slippers" » "python using real slippers", "python using a slippers", "python using low slippers", "python using raw slippery", "python using raw grippers"
"thuc va 07 snippets" » "thuc vat 07 snippets", "thuc dan 07 snippets", "thuc day 07 snippets", "thuc va s7 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 va 07 snippets\") OR (\"python using raw slippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( thuc va 07 snippets ) OR ( python using raw slippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thuc va 07 snippets") OR ("python using raw slippers"))) OR ("locating bug code snippets"))*.
