A first named entity, in a first query, may be identified. A first type, of the first named entity, may be determined and a first prefix and a first postfix, associated with the first named entity in the first query, may be identified. The first prefix and the first postfix may be assigned to a first group. The first group may designate one or more prefixes and one or more postfixes as being associated with the first type. A second named entity, associated with the first prefix and the first postfix in the first group, may be identified in a second query. Responsive to the second named entity being associated with the first type, a first search intent case comprising the first prefix, the first postfix, and the first type may be added to a database.
