Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"lan chi duc snippets" » "luan chi duc snippets", "van chi duc snippets", "san chi duc snippets", "lan chi duoc snippets", "lan chi cuc snippets", "lan chu duc 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 (\"lan chi duc snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( lan chi duc snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("lan chi duc snippets"))) OR ("locating bug core snippets"))*.
