Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"mo co duan snippets" » "mo co dan snippets", "mo co quan snippets", "mo co duong snippets", "moi co duan snippets", "mo cho duan snippets", "mot co duan 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: "((((\"mo co duan snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( mo co duan snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("mo co duan snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
