Perhaps you should try some spelling variations:
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"locating bug core snippets" » "locating bug code snippets"
"o cuoc code snippets" » "cho cuoc code snippets", "dao cuoc code snippets", "doc cuoc code snippets"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("o cuoc code snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))~.
• Removing quotes may allow a broader search: (((( o cuoc code snippets ) or ( python using data snippets ))) or ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("o cuoc code snippets") or ("python using data snippets"))) or ("locating bug core snippets"))*.
