Perhaps you should try some spelling variations:
"python using raw snippets" » "python using real snippets", "python using a snippets", "python using low snippets"
"van chi duc slippers" » "van chien duc slippers", "luan chi duc slippers", "van chat duc slippers", "van chi duoc slippers", "van chi cuc slippers", "van chu duc slippers", "van chi duc slippery", "van chi duc grippers"
"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 raw snippets\") OR (\"van chi duc slippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using raw snippets ) OR ( van chi duc slippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using raw snippets") OR ("van chi duc slippers"))) OR ("locating bug code snippets"))*.
