Perhaps you should try some spelling variations:
"python missing data snippets" » "python using data snippets"
"locating bug core snippets" » "locating bug code snippets"
"mat ca hon snippets" » "mat ca code snippets", "mat cua hon snippets", "mat can hon snippets", "mat ma hon snippets", "mat cao hon snippets", "mat cay hong snippets"

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

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