Perhaps you should try some spelling variations:
"python using sat snippets" » "python using data snippets", "python using a snippets", "python using raw snippets", "python using sat slippers"
"ten hoi dan snippets" » "tan hoi dan snippets", "te hoi dan snippets", "ten goi dan snippets", "ten hoa dan snippets", "ten hoc dan snippets", "ten hoi dap snippets", "ten hoi 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: "((((\"ten hoi dan snippets\") OR (\"python using sat snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( ten hoi dan snippets ) OR ( python using sat snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("ten hoi dan snippets") OR ("python using sat snippets"))) OR ("locating bug code snippets"))*.
