Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"hoi hap dan snippets" » "hoi nhap dan snippets", "hoi dap dan snippets", "ho hap dan snippets", "hoi hat dan snippets", "hoi hai dan snippets", "hoi ham dan snippets", "hoi hap dan 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 (\"hoi hap dan snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( hoi hap dan snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("hoi hap dan snippets"))) OR ("locating bug code snippets"))*.
