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