I am using Apache Solr..I have the following Scenario.. :
I have Two table in my PostGreSQL database. One is \"Cars\". Other is \"D
if the fields are the same for both cars and dealers, you could use one index with an object defined like so:
this will work for both cars and dealers (so you don't need to have 2 indexes) and you'll use the "type" field to sort out if you want a "dealer" or a "car" (i'm using the same system to filter out similar types of objects with only a minor "semanthical" difference)
also you'll need to add stored="true" to the fields you want to retrieve, or you'll be only able to use them for searching (hence that index="true")
