#! (hashbang) check help needed

[raido]

Does anybody have experience using hashbang? We tried to use it to solve indexation problem and I'm not fully sure do we use right solution now (developers did it with these FAQ and Guide to Ajax crawling as information source).

One of our client has problem, that their e-shop categories, has solution where search engines aren't able to index all products. In this example a category, there is this "Näita kõiki (38)" that shows all category products for users but as I understand search engines aren't able to index it as /et#/activeTab=tab02 because of #. Now there is used #! (hashbang) and it is /et#!/activeTab=tab02. Is this correct solution?

Also now example category URL is defferent for better indexation with:
/et#!/
../et

And when tabs "TOP ja uued" and "Näita kõik" where activated/clicked then:
/et#/activeTab=tab01
/et#/activeTab=tab02

I tried to fetch it in Google Webmaster Tools but it seems it didn't work.

I would appreciate it if anybody can check this solution?
