Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"nhan duoc 4 snippets" » "nhan cuoc 4 snippets", "nhan quoc 4 snippets", "phan duoc 4 snippets", "nhan doc 4 snippets", "nhan duoc 1 snippets", "nhan duoc 2 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: "((((\"nhan duoc 4 snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( nhan duoc 4 snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("nhan duoc 4 snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
