CREATE TABLE br_test ( `id` UInt64, `val` String, INDEX ind val TYPE bloom_filter() GRANULARITY 1 ) ENGINE = MergeTree() ORDER BY id SETTINGS index_granularity = 2;

INSERT INTO br_test (id, val) select number as id, toString(number) as val from numbers(100);

SELECT count() FROM br_test WHERE identity(val) = '50';

-- 1 

SELECT count() FROM br_test WHERE val = '50';

-- 0 !!!
