Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"python using raw snippets" » "python using real snippets", "python using a snippets", "python using low snippets", "python using raw slippers"
"van cau duc slippery" » "van dau duc slippery", "van hau duc slippery", "van chat duc slippery", "van cao duc slippery", "van cau luc slippery", "van chu duc slippery", "van cau duc slippers"

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 cau duc slippery\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using raw snippets ) OR ( van cau duc slippery ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using raw snippets") OR ("van cau duc slippery"))) OR ("locating bugs code snippets"))*.
