Problems with advanced search

Hi!,

I have two problems with advanced search.
1. I added a new taxonomy and i want to add it to search because it’s a list of variations. But on Search i cannot access to other taxonomies just location.

There is something i can do to make me able to search in other taxonomies?.

2.- First time i search on country list (location taxonomy) no results appears. After that it shows ‘refresh’ icon then doing the same it gets proper search.

Thanks for you help in advance!!.
