I have large set of documents in index. Earlier some fields are mapped as index = false since client do not wanted to search on these. As per new changes certain fields needs to be set as searchable ( setting index = true ) . Is this recommended to do in production environment ( with put api ) ? Will this hurt cluster ?
Also if i want to add new field as and set it as index = true, would it effect performance of cluster ? How adding fields affect old data which does not have that fields ?
