Perhaps you should try some spelling variations:
"python missing data snippets" » "python using data snippets"
"locating bug core snippets" » "locating bug code snippets"
"cua fan mo snippets" » "cua fan code snippets", "cua ban mo snippets", "cua dan mo snippets", "cua can mo snippets", "cua ran mo snippets", "cua van mo snippets"

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

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