Perhaps you should try some spelling variations:
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"hoi cao code snippets" » "hoi cao cong snippets", "hoi cao de snippets", "hoi cfd code snippets", "hoc cao code snippets", "hoi co code snippets", "hoi cho code 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 data snippets") OR ("hoi cao code snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"python using data snippets\") OR (\"hoi cao code snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( python using data snippets ) OR ( hoi cao code snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("python using data snippets") OR ("hoi cao code snippets"))) OR ("locating bug core snippets"))*.
