Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"n trinh cad snippets" » "n trinh code snippets", "n trinh cau snippets", "n trinh cac snippets", "n trinh cam snippets", "p trinh cad snippets", "anh trinh cad snippets", "dan trinh cad 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: "((((\"n trinh cad snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( n trinh cad snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("n trinh cad snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
