Detailed Description

The conjunction query is a compound query.

The result documents must satisfy all of the child queries. It is possible to recursively nest compound queries.

At execution, a conjunction query that has no child queries is not allowed and will fail fast.

Match documents with "location" in the field reviews.content and true in the field free_breakfast.

auto query = couchbase::conjunction_query{
  couchbase::match_query("location hostel").field("reviews.content"),
  couchbase::boolean_field_query(true).field("free_breakfast")
};
