Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"danh ca co snippets" » "danh ca code snippets", "dan ca co snippets", "doanh cua co snippets", "danh cho co snippets", "danh cac co snippets", "danh cay co snippets", "danh cua co snippets"
"python using java snippets" » "python using data 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: "((((\"danh ca co snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( danh ca co snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("danh ca co snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
