I'm working on a jumbo trie patch (just many smaller trie related issues at once) - SOLR-1288.
Anyway, I think support will be good enough for 1.4 that we should make types like "integer" in the example schema be based on the trie fields. The current "integer" fields should be renamed to "pinteger" (for plain integer), and have a recommended use only for compatibility with other/older indexes. People have mistakenly used the plain integer in the past based on the name, so I think we should fix the naming. The trie based fields should have lower memory footprint in the fieldcache and are faster for a lookup (the only reason to use plain ints in the past)... sint uses StringIndex for historical reasons - we had no other option... we could upgrade the existing sint fields, but it wouldn't be quite 100% compatible and there's little reason since we have the trie fields now. -Yonik http://www.lucidimagination.com
