I am starting to have some fun with PT, exploring more and more.
After having corrupted the database trying to reduce full text index to below 4 letter queries, my hosting company is learning with me :) We decided to ditch that idea.
The pt_products table is become bigger very fast and its really hard to do any operations with it now.
I would like to start using a second installation for book feeds and possibly other large feeds to avoid further growth of that table.
What are the downsides to using a second or even third installation with one WP front-end? What should I pay attention to? Are there any useful threads that you would recommend reading?
