"locating bug core snippets" » "locating bug code snippets"
"using java java snippets" » "using data java snippets"

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"using java java snippets\") OR (\"va cong cong snippets\"))) OR (\"locating bug core snippets\"))*".
• Removing quotes may allow a broader search: (((( using java java snippets ) OR ( va cong cong snippets ))) OR ( locating bug core snippets ))*.
