Perhaps you should try some spelling variations:
"python using code snippets" » "python using cfd snippets", "python using one snippets"
"than hoc can snippets" » "toan hoc can snippets", "thai hoc can snippets", "than doc can snippets", "than hoc dan snippets", "than hoc cao snippets", "than hoc cac snippets"
"locating bug core snippets" » "locating bug code snippets"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("python using code snippets") OR ("than hoc can snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"python using code snippets\") OR (\"than hoc can snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( python using code snippets ) OR ( than hoc can snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("python using code snippets") OR ("than hoc can snippets"))) OR ("locating bug core snippets"))*.
