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