Exists Query

The Exists query is used for returning documents that contain an indexed value for a field.

In order to use the Exists query import the following:

import zio.elasticsearch.query.ExistsQuery
import zio.elasticsearch.ElasticQuery._

You can create an Exists query using the exists method this way:

val query: ExistsQuery = exists(field = "name")

Also, you can create a type-safe Exists query using the exists method this way:

val query: ExistsQuery = exists(field = Document.name)

If you want to change the boost, you can use boost method:

val queryWithBoost: ExistsQuery = exists(field = "name").boost(2.0)
