Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"cong cua o snippets" » "cong cu o snippets", "dong cua o snippets", "huong cua o snippets", "cong cua bo snippets", "cong cua co snippets", "cong chua o 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 (\"cong cua o snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( cong cua o snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("cong cua o snippets"))) OR ("locating bugs code snippets"))*.
