Нow to use Knowledge Management module instead of IRQUEUE for text searching in SD&IM, etc.?

Hello everybody,

we use IRQUEUE for full text searching in SD&IM&IMtasks and so on.

But after the quantity of SD and IM each became more than 1 million of records, the IRQUEUE started to work absolutely unstable, the regeneration executed several days.

In one post I've seen that as a solution it's possible to use Knowledge Management module instead of IRQUEUE, which is new technology.

Does anybody know how to use Knowledge Management module instead of IRQUEUE for text searching in SD&IM?
