Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"cd cao code snippets" » "cd cao cong snippets", "cd cao de snippets", "cd cfd code snippets", "cu cao code snippets", "ca cao 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: (((("cd cao code snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"cd cao code snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))*".
• Removing quotes may allow a broader search: (((( cd cao code snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))*.
