Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"he phap cau snippets" » "he phan cau snippets", "he pha cau snippets", "he phap ca snippets", "che phap cau snippets", "de phap cau snippets", "ve phap cau snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug core 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 (\"he phap cau snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( he phap cau snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("he phap cau snippets"))) OR ("locating bug code snippets"))*.
