ranged and boolean query
hi. i'm using solr and am trying to limit my resultset to documents that either have a publication date in the range * to now, or have no publication date set at all (field is not present). however, using this : (pubdate:[* TO NOW]) OR ( NOT pubdate:*) gives me only the documents in the range * to now (reversing the two clauses has no effect). using only NOT pubdate:* gives me the correct set of documents (those not having a pubddate). any reason the OR does not work in this case ? ps: also tried it like this : pubdate:([* TO NOW] OR (NOT *)) which gives the same result. -- CUL8R, Peter. www.desk.nl --- Sent from my NetBSD-powered Talkie Toaster™

This tells SOLR to exclude the field. Otherwise, the word NOT would be treated as a term, and would be applied against your default field (which may or may not affect your results). So instead of (pubdate:[* TO NOW]) OR ( NOT pubdate:*), you would write (pubdate:[* TO NOW]) OR ( -pubdate:*). - Ken

What's your schema look like? And what does the debug query look like?
