"locating bug core snippets" » "locating bug code snippets"

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"using a java snippets\") OR (\"dat trong code snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( using a java snippets ) OR ( dat trong code snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("using a java snippets") OR ("dat trong code snippets"))) OR ("locating bug core snippets"))*.
