Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"hoc hoi phe snippets" » "hoc khoi phe snippets", "hoc hoa phe snippets", "hoc noi phe snippets", "hoc ho phe snippets", "hoc hoc phe snippets", "hoc hoi phu 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 (\"hoc hoi phe snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( hoc hoi phe snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("hoc hoi phe snippets"))) OR ("locating bug code snippets"))*.
