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