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"
"tri hoc dang snippets" » "tri hoc dan snippets", "tri hoc dung snippets", "tri hoc bang snippets", "triet hoc dang snippets", "tri thuc dang snippets", "thai hoc dang snippets", "tri hoc dang 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 (\"tri hoc dang snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using sat snippets ) OR ( tri hoc dang snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using sat snippets") OR ("tri hoc dang snippets"))) OR ("locating bug code snippets"))*.
