Perhaps you should try some spelling variations:
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"thi hao cao snippets" » "thi thao cao snippets", "thi hai cao snippets", "thi ha cao snippets", "thi bao cao snippets", "thi tao cao snippets", "thi dao cao snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug core 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 data snippets\") OR (\"thi hao cao snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using data snippets ) OR ( thi hao cao snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using data snippets") OR ("thi hao cao snippets"))) OR ("locating bug code snippets"))*.
