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"
"van chi duoc slippery" » "van che duoc slippery", "van cho duoc slippery", "van chet duoc slippery", "van chien duoc slippery", "luan chi duoc slippery", "van chat duoc slippery", "van chi duoc 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: "((((\"python using raw snippets\") OR (\"van chi duoc slippery\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using raw snippets ) OR ( van chi duoc slippery ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using raw snippets") OR ("van chi duoc slippery"))) OR ("locating bug code snippets"))*.
