Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"cum danh mo snippets" » "cum danh code snippets", "cuon danh mo snippets", "nam danh mo snippets", "cum dan mo snippets", "cum danh co snippets", "cum danh o snippets"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data 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: "((((\"cum danh mo snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( cum danh mo snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cum danh mo snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
