Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"dung cau y snippets" » "dung chau y snippets", "dung cu y snippets", "dung cac y snippets", "dung cau _ snippets", "dung cap y snippets", "dung cau o 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: "((((\"python using java snippets\") OR (\"dung cau y snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( dung cau y snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("dung cau y snippets"))) OR ("locating bug core snippets"))*.
