Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"dan hoc la snippets" » "van hoc la snippets", "dan toc la snippets", "dai hoc la snippets", "dan hoc lam snippets", "dan hoc lap snippets", "dan hoc lao snippets", "dan hoc la 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 (\"dan hoc la snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( dan hoc la snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("dan hoc la snippets"))) OR ("locating bug code snippets"))*.
