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