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