Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"using java java snippets" » "using data java snippets"
"vi dinh lap snippets" » "vi dinh lam snippets", "vi trinh lap snippets", "vi dinh lang snippets", "vi sinh lap snippets", "vi tinh lap snippets", "vu dinh lap 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 dinh lap snippets\") OR (\"using java java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( vi dinh lap snippets ) OR ( using java java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vi dinh lap snippets") OR ("using java java snippets"))) OR ("locating bug core snippets"))*.
