Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"dau noi luc snippets" » "cau noi luc snippets", "dang noi luc snippets", "dau cuoi luc snippets", "dau noi suc snippets", "dau voi luc snippets", "dau noi thuc 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: "((((\"dau noi luc snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( dau noi luc snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dau noi luc snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
