Perhaps you should try some spelling variations:
"python missing data snippets" » "python using data snippets"
"locating bug core snippets" » "locating bug code snippets"
"hat cao de snippets" » "hat cao code snippets", "chat cao de snippets", "hat ca de snippets", "hat dao de snippets", "hat nao de snippets"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"hat cao de snippets\") OR (\"python missing data snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( hat cao de snippets ) OR ( python missing data snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("hat cao de snippets") OR ("python missing data snippets"))) OR ("locating bug core snippets"))*.
