Javi, Thanks for answer. As far as i know i can use complex keys (according to couch wiki) my problem was that I didn't understand how to do it. Now my problem is that i can't find way to do "curl http://127.0.0.1:5984/hanh-phuc-sac-dev/_design/staff/_view/all?key=\"cat1\"; from my ruby app. I'm planing to use couchrest_model and if i understand coretly when i add "view_by :category" to my class I can use Item.find_by_category('cat1').
