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"
"thi nhan dan snippets" » "tri nhan dan snippets", "thi than dan snippets", "thi ngan dan snippets", "thi phan dau snippets", "thi gian dan snippets", "thi nhan tai snippets", "thi nhan 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 sat snippets\") OR (\"thi nhan dan snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using sat snippets ) OR ( thi nhan dan snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using sat snippets") OR ("thi nhan dan snippets"))) OR ("locating bug code snippets"))*.
