Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"duc hung le snippets" » "duc hung code snippets", "quoc hung le snippets", "duc nhung le snippets", "duc dung le snippets", "duc hong le 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: "((((\"python using java snippets\") OR (\"duc hung le snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( duc hung le snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("duc hung le snippets"))) OR ("locating bug core snippets"))*.
