Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"dan chi hoa snippets" » "dan chi code snippets", "danh chi hoa snippets", "dan thi hoa snippets", "van chi hoa snippets", "dan chi khoa snippets", "dan chi hoat snippets"
"python using java snippets" » "python using 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: "((((\"dan chi hoa snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( dan chi hoa snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dan chi hoa snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
