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
