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"
"pha hoc sach snippets" » "pha hoc sinh snippets", "pha hoc cac snippets", "pha hoc anh snippets", "phap hoc sach snippets", "phau hoc sach snippets", "nha hoc sach snippets", "pha hoc sach 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: "((((\"pha hoc sach snippets\") OR (\"python using sat snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( pha hoc sach snippets ) OR ( python using sat snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("pha hoc sach snippets") OR ("python using sat snippets"))) OR ("locating bug code snippets"))*.
