Perhaps you should try some spelling variations:
"python using code snippets" » "python using cfd snippets", "python using one snippets"
"locating bug core snippets" » "locating bug code snippets"
"thi dan de snippets" » "thi doan de snippets", "thi lan de snippets", "thi dai de snippets", "thi dan den snippets", "thi dang de snippets", "thi van de 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: (((("thi dan de snippets") OR ("python using code snippets"))) OR ("locating bug core snippets"))~.
• Removing quotes may allow a broader search: (((( thi dan de snippets ) or ( python using code snippets ))) or ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thi dan de snippets") or ("python using code snippets"))) or ("locating bug core snippets"))*.
