SUBSTANCE: server receives an indication of the user request, uses the first model to generate a first candidate string and a second candidate string that represent the corresponding candidates for the extended query, uses the second model to determine that the first string is candidate and the second candidate string are a pair of similar candidate strings, and causes only one of the pair of similar candidate strings to be displayed on the electronic device as an extended query. The second model is trained in a pairwise configuration based on the training set. The training set contains the first and second training lines and a label. The label indicates the similarity of the first training string and the second training string.
