if i may ask: did you customize the Solr code at all (ie: are you using any custom request handlers, field types or your own Similarity class) ? ... if not, which request handler are you using (Standard or DisMax) ?
I'm using the Solr from the nightly build, with Standard request handler, and have made no code modifications. I do some pre-parsing of the users query so it searches the right fields and doesn't throw off Lucene with anything unexpected. I added several custom fields, and modified the TextField in schema.xml for some things that are specific to the app, like disabling stemming and stop words, and using ISOLatin1FilterFactory (so searches for "bjork" will find "björk", etc).
