Thanks Yonik, Is this something you might have time to throw together, or an outline of what needs to be thrown together? Is this something that should be asked on the developer's list or discussed in SOLR 1715 or does it make the most sense to keep the discussion in this thread?

Yeah, I've thought about a special query parser and query to deal with this (relatively) efficiently, both from a query perspective and a memory perspective. Should be pretty quick to throw together: - comma separated list of terms (unique ids are a special case of this) - in the query, store as a single byte array for efficiency - sort the ids if they aren't already sorted - do lookups with a term enumerator and skip weighting or anything else like that - configurable caching... may, or may not want to cache this big query That's only part of the stuff you mention, but seems like it would be useful to a number of people. -Yonik http://www.lucidimagination.com
