Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"dung cua so snippets" » "dung cua code snippets", "dung luan so snippets", "dung cho so snippets", "dung cua sro snippets", "dung cua bo snippets", "dung cua su 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: "((((\"dung cua so snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( dung cua so snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung cua so snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
