Abstract: Techniques for searching documents are described. An exemplary method includes receiving a document search query; querying at least one index based upon the document search query to identify matching data; fetching the identified matched data; determining one or more of a top ranked passage and top ranked documents from the set of documents based upon one or more invocations of one or more machine learning models based at least on the fetched identified matched data and the document search query; and returning one or more of the top ranked passage and the proper subset of documents.

Abstract: Techniques for active learning for document querying machine learning (ML) models as a service are described. A service may perform a search of data of a user, using a machine learning model, for a search query to generate a result, generate a confidence score for the result of the search, select a proper subset of the data to be provided to the user based on the confidence score, display the proper subset of the data to the user, receive an indication from the user of one or more sections of the proper subset of the data for use in a next training iteration of the machine learning model, and perform the next training iteration of the machine learning model with the one or more sections of the proper subset of the data.
