Is there an api in Lucene for finding the similarity score for two documents that have been randomly pulled from an index? What about for a query and a randomly selected document?
I realize this isn't the standard purpose of Lucene, but I was given a task to compare similarity scores for the Similarity classes defined in Lucene 4.x using a somewhat large predefined set of documents and query strings, and I am finding that collecting the results by indexing the documents in separate indexes with each of the Similarity classes, searching using the query strings, locating the subset of documents in the results that I am interested in and recording the scores is taking quite a long time. I am about to look through the Lucene source code to see how the Similarity classes are used in normal use cases such as search and more-like-this, but if someone could direct me on where to look, or, even better, knows of an api function that takes a pair of documents, or a query and a document, and returns a similarity score for them, I would greatly appreciate it. Thanks, Mike
