I am using Apache Solr..I have the following Scenario.. :
I have Two table in my PostGreSQL database. One is \"Cars\". Other is \"D
Adding a default value to the type field will ensure the type value being set to cars|dealer
.
You will have to index the sources separately. Then use copy field and you can easily filter on either cars|dealer
.
This does seem a bit tricky and is not explained well in the muti-indexes link referred to above.
