Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"quan ca dan snippets" » "quan cua dan snippets", "quan cau dan snippets", "quan ha dan snippets", "quan cac dan snippets", "quan ca dao snippets"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("quan ca dan snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"quan ca dan snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))*".
• Removing quotes may allow a broader search: (((( quan ca dan snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))*.
