# `SearchQueryExpression` interface

A polymorphic query expression allowing operator expression nesting of the different query expressions. The expressionType discriminator is selectable without an inline fragment; every other field requires a fragment on the concrete type. Note that GraphQL field merging still requires one type per response name across fragments — the differently-typed leaf value fields are named intValue / timeValue / boolValue / value for that reason.
