Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"trinh va vu snippets" » "trinh van vu snippets", "trinh vat vu snippets", "trinh ve vu snippets", "trinh va vua snippets", "trinh va su snippets", "trinh va tu snippets", "trinh va 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: "((((\"python using java snippets\") OR (\"trinh va vu snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( trinh va vu snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("trinh va vu snippets"))) OR ("locating bug code snippets"))*.
