1. A method for performing similarity searching, comprising the steps of: receiving a request instruction from a client for initiating a similarity search; generating one or more query commands from the request instruction, each query command designating an anchor document and at least one search document; executing each query command, including: computing a normalized document similarity score having a value of between 0.00 and 1.00 for each search document in each query command for indicating a degree of similarity between the anchor document and each search document; creating a result dataset containing the computed normalized document similarity scores for each search document; and sending a response including the result dataset to the client.
