Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"x phan code snippets" » "x phan cong snippets", "x phan co snippets", "x phan che snippets", "xa phan code snippets", "d phan code snippets", "a phan code snippets"
"locating bug core snippets" » "locating bug 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 (\"x phan code snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( x phan code snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("x phan code snippets"))) OR ("locating bug core snippets"))*.
