Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"tu can danh snippets" » "tu van danh snippets", "tu cao danh snippets", "tu cau danh snippets", "tu ban danh snippets", "tu cac danh snippets", "su can danh snippets", "tu can 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: "((((\"tu can danh snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( tu can danh snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("tu can danh snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
