Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"su cuu danh snippets" » "su cuu anh snippets", "su cum danh snippets", "su cau danh snippets", "su cu danh snippets", "su cua danh snippets", "so cuu danh snippets", "su cuu danh 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: "((((\"su cuu danh snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( su cuu danh snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("su cuu danh snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
