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"
"cau danh tu snippets" » "cao danh tu snippets", "chuc danh tu snippets", "nam danh tu snippets", "cau anh tu snippets", "cau hanh tu snippets", "cau doanh thu 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: "((((\"cau danh tu snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( cau danh tu snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cau danh tu snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
