How to redirect the main page?

Question

Yii

Hello. I need to make the main page at /catalog/shares, catalog is a module, it has a default controller, it has an index method, and the index method takes the shares parameter, how to do this?
Tried this and that but it doesn't work '/' => 'catalog/default/index/shares''/' => 'catalog/shares'

Answer 1

main and takes a parameter, somehow incompatible, but apparently like this:
and if the link looks like
mysite.com?shares=chtoto
then like this
'/' => 'catalog/default/index'
