Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"dung cac ba snippets" » "luong cac ba snippets", "dung cho ba snippets", "dung tai ba snippets", "dung cac bai snippets", "dung cac ban snippets", "dung cac bac 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: "((((\"dung cac ba snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( dung cac ba snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung cac ba snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
