Here we are trying to explain the design approaches when we integrate Solr search with AEM
Solr with CQ : Better designs
When we are in designing phase of Solr search with CQ, we have different approaches. One of the better approach is explained below.
How many Solr in production environment?
For the System to handle abundant requests and fail safe condition met, we need to have minimum two Solr instances set up and a load balancer on it. So when ever there is a request the load will be balanced and request will be served.
How the update works?
For updating both Solr through load balancer, we need to have Apache ZooKeeper configured(http://zookeeper.apache.org/). Zookeeper helps us to serve the configurations across server.
Can we have xslt transformation for JSON through this design?
Yes. When we need JSON response from Solr, we have to use our own xslt files for transformation. This can be kept as usual inside Solr deployed server (For eg : JBoss).
My changes on xslt not appearing in server. How to fix?
After xslt changes, some times the server cache xslt files. To get the xslt files refreshed, we need to follow below steps.

- Stop JBoss
- Stop ZooKeeper
- Clear temp folders of JBoss
- Start JBoss,ZooKeeper
