Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"danh ca su snippets" » "dan ca su snippets", "doanh cua su snippets", "danh cho su snippets", "danh cua su snippets", "danh cao su snippets", "danh ca sau snippets", "danh ca su 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: "((((\"danh ca su snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( danh ca su snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("danh ca su snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
