Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using raw snippets" » "python using real snippets", "python using a snippets", "python using low snippets"
"tri tho dan snippets" » "tri nho dan snippets", "thi tho dan snippets", "tri thuoc dan snippets", "tri thuc dan snippets", "tri choi dan snippets"

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

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