Re: Compass vs Solr
If your question is about 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.

The search is across different types of data, so it does not scale well from the database. As lucene does not allow to store relational data, we decided to try out Compass since it provides a object relation mapping to the lucene index. We have got good results with compass when compared to the database search. But before we migrate the all the other search workflows to use compass, we are trying to evaluate Solr. We will need to scale our application as our data is increasing by the day. Can anyone suggest which one would perform/scale well Compass or Solr? OR Has anyone tried to use a combination of Compass Solr? Any suggestion would be appreciated. Thanks, Harini
Re: Compass vs Solr
compass is nice: you install it and it just works. I was totally impressed. Can anyone suggest which one would perform/scale well Compass or Solr? It depends on what your app looks like. 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) Has anyone tried to use a combination of Compass Solr? I am using a hibernate event watcher to automatically store stuff to solr when an object is changed. http://solrstuff.org/svn/solrj-hibernate/src/org/apache/solr/client/solrj/hibernate/SolrSync.java The code is dependent on an old version of SOLR-20. I'll update it later this week after SOLR-20 gets added to the official solr.
