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