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"
"cau den cac snippets" » "cap den cac snippets", "cau de cac snippets", "hau den cac snippets", "cau dien cac snippets", "cau dan cac 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 ("cau den cac snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"python using code snippets\") OR (\"cau den cac snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( python using code snippets ) OR ( cau den cac snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("python using code snippets") OR ("cau den cac snippets"))) OR ("locating bug core snippets"))*.
