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