Perhaps you should try some spelling variations:
"python missing data snippets" » "python using data snippets"
"locating bug core snippets" » "locating bug code snippets"
"tap du 3 snippets" » "thap du 3 snippets", "lap du 3 snippets", "tap de 3 snippets", "tap du _ snippets", "tap do 3 snippets", "tap du f 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: "((((\"tap du 3 snippets\") OR (\"python missing data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( tap du 3 snippets ) OR ( python missing data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("tap du 3 snippets") OR ("python missing data snippets"))) OR ("locating bug core snippets"))*.
