multiple domain, same wp_post, serving each domain through custom taxonomy

Hi guys,

I am trying to figure out what the best way is to realize this.

I have multiple blogs running on separate domains. I recently merged the post data from the different blog into one wp database where all post live in the same wp_post table. I build a custom taxonomy to differentiate which post belongs to which blog.

So I have:

https://www.blog1.com
https://www.blog2.com
https://www.blog3.com

one wp_post table with post for all three blogs.

custom taxonomy called ‘Domain’ with value ‘blog1’ ‘blog2’ ‘blog3’

And each blog needs to have it’s own theme.

And I need to be able to search across all blogs. (that’s why I put all post in one table)

Is this possible to realize?

I thought about rewriting the different domains within wordpress (or using plugins like MiniMU) or using mod_rewrite to hide the fact that all blog are running on one wp instance.

Does anybody have a better solution for this. Nothing is set in stone except multiple domains, different post, different theme and search. I am open to any suggestion to architect this in a better way.

Thanks a lot
