Hi hopefully simple questions.

Experienced joomla user not with K2 however.

1. Can you use K2 to create a listing site (yes I know) that agents can register an account and list their own properties?
(I dont want to use hotproperty for this)

2. What is the best search plugin for faceted (aka filtered) search? Im looking at Solr hopefully.

3. What plugins are required to make this work? At this stage I dont need to charge agents money if they want to list, they simply need to just create an account and list themselves.

4. What is the largest k2 site? Can it handle 500 000 + records?

nobody?
