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 bo dan snippets" » "thi bao dan snippets", "thi mo dan snippets", "thi ba dan snippets", "thi co dan snippets", "thi so dan snippets", "thi bo dao 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 ("thi bo dan snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"python using code snippets\") OR (\"thi bo dan snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( python using code snippets ) OR ( thi bo dan snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("python using code snippets") OR ("thi bo dan snippets"))) OR ("locating bug core snippets"))*.
