Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"vi duong co snippets" » "vi duong code snippets", "vi luong co snippets", "va duong co snippets", "vu duong co snippets", "vi dong co snippets", "vi dung co snippets"
"using java java snippets" » "using data java 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: "((((\"vi duong co snippets\") OR (\"using java java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( vi duong co snippets ) OR ( using java java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vi duong co snippets") OR ("using java java snippets"))) OR ("locating bug core snippets"))*.
