Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"den dong ha snippets" » "dien dong ha snippets", "dan dong ha snippets", "de dong ha snippets", "den dong hoa snippets", "den dong va snippets", "den dong hoc 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: "((((\"den dong ha snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( den dong ha snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("den dong ha snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
