Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"dang a core snippets" » "dang ha core snippets", "dang va core snippets", "dang ba core snippets", "dang _ core snippets", "dang a care snippets", "dang a corn snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code 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 (\"dang a core snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( dang a core snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("dang a core snippets"))) OR ("locating bug code snippets"))*.
