Perhaps you should try some spelling variations:
"python missing data snippets" » "python using data snippets"
"locating bug core snippets" » "locating bug code snippets"
"dan a ho snippets" » "dan a code snippets", "dan ca ho snippets", "dan va ho snippets", "dan ap ho snippets", "dan la ho snippets", "dan x ho 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: "((((\"dan a ho snippets\") OR (\"python missing data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( dan a ho snippets ) OR ( python missing data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dan a ho snippets") OR ("python missing data snippets"))) OR ("locating bug core snippets"))*.
