Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"mat da cho snippets" » "mat dan cho snippets", "mat ma cho snippets", "vat da cho snippets", "mat dac cho snippets", "mat day cho 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: (((("mat da cho snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))~.
• Removing quotes may allow a broader search: (((( mat da cho snippets ) or ( python using java snippets ))) or ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("mat da cho snippets") or ("python using java snippets"))) or ("locating bug code snippets"))*.
