Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets", "python using data slippers"
"dao o duc snippets" » "dao _ duc snippets", "dao do duc snippets", "dao ho duc snippets", "dao oi duc snippets", "dao o duc slippers"

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: "((((\"dao o duc snippets\") OR (\"python using data snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( dao o duc snippets ) OR ( python using data snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dao o duc snippets") OR ("python using data snippets"))) OR ("locating bugs code snippets"))*.
