Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"manh hung cac snippets" » "manh hung code snippets", "anh huong cac snippets", "manh dung cac snippets", "manh hang cac snippets", "manh vung cac 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: "((((\"using java java snippets\") OR (\"manh hung cac snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using java java snippets ) OR ( manh hung cac snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java java snippets") OR ("manh hung cac snippets"))) OR ("locating bug core snippets"))*.
