Perhaps you should try some spelling variations:
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets", "python using data slippers"
"dai co dan snippets" » "mai co dan snippets", "dai so dan snippets", "tai co dan snippets", "dai co ban snippets", "dai ca dan snippets", "dai cao dang snippets", "dai co dan 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 data snippets\") OR (\"dai co dan snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using data snippets ) OR ( dai co dan snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using data snippets") OR ("dai co dan snippets"))) OR ("locating bug code snippets"))*.
