1. A method for normalizing confidence score thresholds, comprising: receiving, by a first hub of a plurality of hubs of a federated environment, a first search query from a calling application; generating, by the first hub, a first confidence score for a result of the first search query; calculating, by one or more computer processors, a normalized confidence score threshold for a second hub of the plurality of hubs of the federated environment by applying a first normalization factor associated with the second hub to the first confidence score; transmitting, from the first hub to the second hub, a second search query with the normalized confidence score threshold calculated for the second hub; and receiving, by the first hub from the second hub, one or more results of the second search query that satisfy the normalized confidence score threshold calculated for the second hub.
