: It probably would simplify some logic to assume unique keys are : required, but we should think a little on it first. Would it make it : harder to model existing random lucene indicies?
yeah ... because then people would be force client side to generate an arbitrary unique key for each doc ... if we really wnat to go this route 9and i don't see any reason why we should) we should make sure we support an autoincrment counter as a default field value so people who don't care about document uniqueness don't have to do anything new to keep using Solr (or to migrate from Lucene to Solr) -Hoss
