Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"cot hat dan snippets" » "cot hat van snippets", "cot mat dan snippets", "cot nhat danh snippets", "cost hat dan snippets", "cot hat 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: "((((\"cot hat dan snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( cot hat dan snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cot hat dan snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
