Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"xanh a da snippets" » "xanh va da snippets", "xanh ai da snippets", "xanh ca da snippets", "anh a da snippets", "hanh a da snippets", "danh a da 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: "((((\"xanh a da snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( xanh a da snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("xanh a da snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
