Detailed Description

The numeric range query finds documents containing a numeric value in the specified field within the specified range.

Either min or max can be omitted, but not both.

By default, min is inclusive and max is exclusive.

Match documents where field id contains numbers in the range (100, 1000):

auto query = couchbase::numeric_range_query()
               .field("id")
               .min(100, /* inclusive= */ false)
               .max(1000, /* inclusive= */ false);
