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