Necessary to close() IndexSearcher in 4.X?

[Lewis John Mcgibbney]

Hi,
I am encountering many situations where searcher.close() is present in
finally blocks such as

        } finally {
            if (searcher != null) {
                try {
                    searcher.close();
                } catch (Exception ignore) {
                }
                searcher = null;
            }
        }

Is some similar implementation still necessary in the 4.X API?

Thank you very much

Lewis
