How elastic search works?

We are upgrading from Pega 7.1.7 to Pega 7.1.9 and changing the indexing mechanism from lucene to elastic.

 

We previously used to have customised solution where the searching of indexes used to be directly from each node to the shared mount accessible on all the nodes.

 

With elastic search we would like to use the distributed way.

 

Few questions:-

 

1. What is the minimum number of nodes that needs to serve as indexing nodes?

2. Host nodes for indexing will be used for both generation and retrieval as well?

3. Would like to understand how the search works with elastic indexes from a node that is not the host node. Does it check initially whether the location is directly accessible or always goes to the host nodes?
