Perhaps you should try some spelling variations:
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"cua gian le snippets" » "cua giang le snippets", "cua giao le snippets", "cua gia le snippets", "cua gian ve snippets", "cua gian e 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 (\"cua gian le snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using data snippets ) OR ( cua gian le snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using data snippets") OR ("cua gian le snippets"))) OR ("locating bug code snippets"))*.
