: dateorigin_sort:"" gives a syntax error. I'm using Solr 1.2. Should : this work in Solr 1.3? Is it legal in a newer Lucene parser?
Hmm.. not sure. did you try the range query suggestion? ... : well, technically range queries "work" they just don't "work" on numeric : ranges ... they'd be lexigraphical ranges on the string value, so... : : dateorigin_sort:[* TO " "] : : ...could probably help you find anything that is lexigraphically lower : then a string representation of an integer (assuming dateorigin_sort:"" : doesn't work) -Hoss
