Message search limitations

Hello, I’m investigating the possibilities of message-search.

In the platform API documentation there’s a notation about a limit of 100 channels being searched (Search a message | Chat Platform API | Sendbird Docs).

In the JS SDK documentation there is no such notation. Does this mean that using the SDK there is no limit on the number of channels that is searched/queried? Does this only include channels the user has joined, or does it search all channels?

Are there any other limitations or boundaries I should consider in my solution design?

thanks in advance!
