Hi, I am trying to join across multiple cores using query time join. Following is my setup 3 cores - Solr 4.7 core1: 0.5 million documents core2: 4 million documents and growing. This contains the child documents for documents in core1. core3: 2 million documents and growing. Contains records from all users.
core2 contains documents that are accessible to each user based on their permissions. The number of documents accessible to a user range from couple of 1000s to 100,000. I would like to get results by combining all three cores. For each search I get documents from core3 and then query core1 to get parent documents & then core2 to get the appropriate child documents depending of user permissions. I 'm referring to this link to join across cores http://stackoverflow.com/questions/12665797/is-solr-4-0-capable-of-using-join-for-multiple-core {!join from=fromField to=toField fromIndex=fromCoreName}fromQuery This is not working for me. Can anyone suggest why it is not working. Any pointers on how to search across multiple cores. thanks J
