Perhaps you should try some spelling variations:
"hoi dan chan snippets" » "hoi dan code snippets", "hoi dan gian snippets", "hoi dan ca snippets", "hoi van chat snippets", "hoa dan chan snippets", "hoc dan chan snippets", "hoi dap chan snippets"
"locating bug core snippets" » "locating bug code snippets"
"python using sat snippets" » "python using data snippets", "python using a snippets", "python using raw snippets"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("python using sat snippets") OR ("hoi dan chan snippets"))) OR ("locating bug core snippets"))~.
• Removing quotes may allow a broader search: (((( python using sat snippets ) or ( hoi dan chan snippets ))) or ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using sat snippets") or ("hoi dan chan snippets"))) or ("locating bug core snippets"))*.
