Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"danh cac co snippets" » "danh cac code snippets", "dinh cac co snippets", "danh ca co snippets", "hanh cac co snippets", "danh cac cong snippets"
"python using sat snippets" » "python using data snippets", "python using a snippets", "python using raw 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: "((((\"danh cac co snippets\") OR (\"python using sat snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( danh cac co snippets ) OR ( python using sat snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("danh cac co snippets") OR ("python using sat snippets"))) OR ("locating bug core snippets"))*.
