Perhaps you should try some spelling variations:
"dat cau code snippets" » "dat cau cong snippets", "dat cau de snippets", "dat cfd code snippets", "dat cau code slippers"
"python using a snippets" » "python using a slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code 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: "((((\"python using a snippets\") OR (\"dat cau code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using a snippets ) OR ( dat cau code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using a snippets") OR ("dat cau code snippets"))) OR ("locating bug code snippets"))*.
