I have an application i am making with time series based date. I was going to have indexes for for each Week, and going to have alieses for 1month, 3 months and then historical. And then for eaech cusotmer I was going to have there data filtered during query time. Now I was watching and reading that a filter can be applied per index and even used per cusotmer, which sounds great but sounds like i could be having a lot of aleies I am not sure what the over head of each alies is and if there is some improvement when using filters on the alies level vs the query time level. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
