A count request executes a query and returns a count of the number of matching documents for that query. It can be executed across one or more indices and across one or more types. The query can be omitted for a total count across the indexes.
To count all documents in an index regardless of type, we can do this.
client.execute {
count from "places"
}
Or then narrow it down by a type.
client.execute {
count from "places"->"london"
}
We can do multiple indexes and multiple types at once.
client.execute {
count from Seq("places", "movies") types ("london", "paris", "scifi")
}
We can include a query to narrow down the results.
client.execute {
count from "places" -> "london" where "borough" -> "westminster"
}
Also where
is a synonym for query
, so you could do
client.execute {
count from "places" -> "london" query "borough" -> "westminster"
}
You can include any part of the QueryDSL inside the where clause.
