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