persistent://public/default/extract-text-.* does match everything topic starts with extract-text?

Describe the bug
I am using the python client with pulsar 2.4.2. I made a subscription with persistent://public/default/extract-text-.* expecting that it would subscribe to all topics that start with extract-text but instead pulsar just creates a topic called persistent://public/default/extract-text-.*? Is this a bug or is there a different syntax to subscribe to all topics starting with extract-text?

[Phat-Loc]

The multi topic feature does not work as documented. Here is a simple test to show

bin/pulsar-client consume my-topic-.* -s "first-subscription"

That should make a subscription to all topics that start with my-topic-

That means the consumer should receive a message from producer publishing to my-topic-hello

bin/pulsar-client produce my-topic-hello --messages "hello-pulsar"

It doesn't. Something is broken or the documentation is wrong.

@pl6306 This is not supported in client tools like bin/pulsar-client. But it should be supported in python client.
What is your python code looks like?

Here is the test code that cover's this case:
test_topics_pattern_consumer

Thanks I get it now. I have to do re.compile first.
