We have a spring project with object models using pojo and we wanted to save the index to the database. Compass was designed with these sorts of features built in.
Here's some of the research I did, hopefully you find something useful in there...
Thinking outloud, "Compass handles the conversion from POLO to XML behind the scenes already and has a bean class for Spring. Hmmm I should search see if there is anything already written on this..."
*** 1. From http://email@example.com/msg04360.html ... If you need to update the index from multiple computers at the same time (load balancing) - solr is the much better approach. If you can write your index all at once and it does not need to be updated from multiple sources - you are fine with either approach. If you don't need fine control of how fields are indexed, compass is fine. Solr lets you configure things like stopwords, synonyms, soundex, spellchecking. You can't search across multiple types in a single query. With solr you will need to explicitly write the Object -> Document conversion. It does not have the nice annotated class helper (yet) *** 2. From http://firstname.lastname@example.org/msg04354.html ...scaling only, I'd put my money on Solr when compared to Compass&Lucene if you are looking at the OO(T?)B offering. Check the Solr Wiki for Master/Slave information. If you go with Compass&Lucene, you'll need to do implement something like that yourself.
*** 3. Another site http://bambarbiakirkudu.blogspot.com/2009/01/solr-lucene-hbase-vs-dbsightcompass-sql.html There a lot there that I'm not clear about what I'm reading.

From my understanding Compass when using their plugin with Terracotta, Gigaspaces,or Coherence..one can implement the same type of scalability that Solr provides with master/Slave configuration even with the possibly improved performance(in memory grid/network attached memory) so you don't have to "implement something like that yourself"
I would too prefer Solr over Compass . My inclination towards Solr is simply because of the kind of power it offers to a user. I think currently the growing volume of data has triggered a need for advancements in techniques. The facilities like interactive text based querying & flexible full text search provided by Solr , do the job fairly well . You can just check out the below mentioned link , as I found it very useful:
