Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"dan viet vu snippets" » "danh viet vu snippets", "san viet vu snippets", "dao viet vu snippets", "dan viet tu snippets", "dan viet du snippets", "dan viet va snippets", "dan viet vu 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: "((((\"dan viet vu snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dan viet vu snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dan viet vu snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
