Perhaps you should try some spelling variations:
"python using raw snippets" » "python using real snippets", "python using a snippets", "python using low snippets", "python using raw slippers"
"ca dan cach slippery" » "ca dan cac slippery", "ca dan canh slippery", "ca nhan cach slippery", "cac dan cach slippery", "ca dao cach slippery", "ca dan cach slippers"
"locating bug code snippets" » "locating bug code slippers", "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: "((((\"ca dan cach slippery\") OR (\"python using raw snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( ca dan cach slippery ) OR ( python using raw snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("ca dan cach slippery") OR ("python using raw snippets"))) OR ("locating bug code snippets"))*.
