Claim:
1. A method for evaluating a search process, the method comprising: receiving, at a computer system comprising a processor, information identifying, in a collection of documents, a first set of documents that satisfies search criteria associated with a first search; determining a document feature vector for each document in the first set of documents; determining a first featured vector comprises at least one of the document feature vectors of the first set of documents; identifying, in the collection of documents, respective documents that do not satisfy the search criteria associated with the first search; receiving information identifying, in the respective documents, a second set of documents that satisfy first sampling criteria, wherein the second set of documents does not comprise all of the respective documents; determining a document feature vector for each document in the second set of documents; determining a second featured vector representing the second set of documents, wherein the second featured vector comprises at least one of the document feature vectors of the second set of documents; determining whether a second search within the respective documents that do not satisfy the search criteria associated with the first search causes new document gain relative to the first search based on a measure of similarity between the first featured vector and the second featured vector exceeding a predetermined threshold value, wherein the second search is associated with the criteria of the first search; generating information indicative of whether the second search of the collection of documents causes new document gain; and displaying to a user of the generated information.
