support Exists query

[yunj]

Does the current client support exists query? There was an old PR for adding support to Exists query, but it's been closed without merging.

Please advise. Thanks.

Hi @yunj,

the current client exposes only documentExistsById(index: Index, tpe: Type, id: String) function.

If you are interested in exists based on query, we don't have such method implemented. What I'm suggesting is to use count(index: Index, tpe: Type, query: QueryRoot) with terminateAfterOpt set to Some(1) and then exists = count > 0
