I create a ilm policy, then index template\_A  
Can I apply the index template\_A to two different index. e.g index\_A\* and index\_B\*.  
If yes how to set the rollover\_alias in the template's setting?

# ============================================= { "index": { "lifecycle": { "name": "plan\_a\_policy", "rollover\_alias": "index\_A" } } }

Or I need to create template per index?

my index like these  
index\_A\_yyyy.mm.dd  
index\_B\_yyyy.mm.dd
