Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"len con coc snippets" » "len cong coc snippets", "lon con coc snippets", "le con coc snippets", "len con cac snippets", "len con co 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.

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