Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"tra du nhat snippets" » "tra do nhat snippets", "tra du chat snippets", "tra lu nhat snippets", "tra tu nhat snippets", "tran duc nhat snippets", "tran duy nhat snippets", "tra du nhat 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: "((((\"tra du nhat snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( tra du nhat snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("tra du nhat snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
