Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"ban da nhap snippets" » "ban dai nhat snippets", "ban dac nhan snippets", "ban gia nhap snippets", "ban dan nhap snippets", "ban dau nhap snippets", "ban dac nhap snippets", "ban da nhap slippers"
"locating bug code snippets" » "locating bug code slippers", "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: "((((\"ban da nhap snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( ban da nhap snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("ban da nhap snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
