Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"duc hanh le snippets" » "duc hanh code snippets", "duc thanh le snippets", "duc anh le snippets", "du hanh le snippets", "duc hanh ve snippets", "duc hanh de 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 hanh le snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( duc hanh le snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("duc hanh le snippets"))) OR ("locating bug core snippets"))*.
