ScyllaDB CQL是否支持`contains`关键字？

Question

在文档中找不到有关该信息的任何信息。如果是的话，我做错了什么？

cqlsh:test_keyspace> select * from id_index limit 1;

 test_keyspace_id
----------------------------------------
 prefix-007

(1 rows)
cqlsh:test_keyspace> select * from id_index where test_keyspace_id contains 'prefix';

 test_keyspace_id
---------------

(0 rows)
cqlsh:test_keyspace> describe id_index

CREATE TABLE test_keyspace.id_index (
    test_keyspace_id text PRIMARY KEY
) WITH bloom_filter_fp_chance = 0.01
    AND caching = '{"keys":"ALL","rows_per_partition":"ALL"}'
    AND comment = ''
    AND compaction = {'class': 'SizeTieredCompactionStrategy'}
    AND compression = {'sstable_compression': 'org.apache.cassandra.io.compress.LZ4Compressor'}
    AND dclocal_read_repair_chance = 0.1
    AND default_time_to_live = 0
    AND gc_grace_seconds = 864000
    AND max_index_interval = 2048
    AND memtable_flush_period_in_ms = 0
    AND min_index_interval = 128
    AND read_repair_chance = 0.0
    AND speculative_retry = '99.0PERCENTILE';

Answer 1

  

CONTAINS运算符只能用于集合列（列表，   集和地图）。在地图的情况下，CONTAINS适用于地图   值。 CONTAINS KEY运算符只能用于地图列和   适用于地图键。

Answer 2

CONTAINS关键字仅适用于集合。我期待的功能是LIKE关键字
