Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"mac cao dan snippets" » "mach cao dan snippets", "mac ca dan snippets", "bac cao dan snippets", "mac cao dang snippets", "mac cao danh snippets", "mac cac dan snippets", "mac cao 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 (\"mac cao dan snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( mac cao dan snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("mac cao dan snippets"))) OR ("locating bug code snippets"))*.
