Perhaps you should try some spelling variations:
"toan cao dang snippets" » "toan ban dang snippets", "toan tap dang snippets", "toan cao dang slippers", "toan cao dan snippets", "toan cao dung snippets", "toan cao dong snippets"
"python using a snippets" » "python using a 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 a snippets\") OR (\"toan cao dang snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using a snippets ) OR ( toan cao dang snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using a snippets") OR ("toan cao dang snippets"))) OR ("locating bug code snippets"))*.
