Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"dan cua cu snippets" » "dan ca cu snippets", "ban cua cu snippets", "dai cua cu snippets", "dan cua chu snippets", "dan cua su snippets", "dan cua co 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 (\"dan cua cu snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( dan cua cu snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("dan cua cu snippets"))) OR ("locating bugs code snippets"))*.
