Updating seachClient keeps the api working with the previous client/apikey

[Intz2010]

How to reproduce?

Using the base example of instant search with config object .
The config object includes the search clinet .

But when I change the searchClient (by call to algoliasearch with different params) or the config object . The client did not changed .

So the next requests will still based on the previous apiKey abd previous searchClient

Is there any solution without rendering whole page ?

I have tried to stop the cache mechanism that I saw in previous question but this is will not change the search client

Thanks
