Hi SN, The latest stable Solr release is Solr 3.3, with 3.4 coming this month. Solr 4.0 and Lucene 4.0 are both not yet stable, as we are still changing APIs and optimizing things like the index format, algorithms. You can use Solr 4.0 snapshot, if you really need the new features and report back what you find out. But you need to know, that we might change index formats from one day to the other, so after an upgrade to a later trunk version, your indexes may no longer be readable and throw scary Exceptions when reading indexes. Upgrading 3.x index formats to 4.0 unstable is always possible, just not 4.0-old to 4.0-new, so be prepared to reindex your stuff after upgrade. Otherwise, Lucene/Solr 4.0 seems quite stable if you don't upgrade.
The Solr version Lucid Imagination ships with LucidWorks, also uses the "unstable" 4.0 version internally, but they guarantee, that you can upgrade between different LucidWorks versions (they provide an index upgrade tool). About the Geo features: I am not familiar with the current status of Solr's Geo support. Maybe somebody else can answer, if the mentioned query type works with the stable version 3.x.
