Queries and Documents in my collection have multiple fields: some numeric and some textual. I know how to define custom Similarity classes per field in Lucene: so I have my textualSimilarity (tf.idf based) and a numericalSimilarity class (both extending Similarity)
I'm now studying how to implement such numericalSimilarity. I have a math formula " (queryNumber - docNumber) / normalization factor) to define the similarity between numeric fields. But how can I implement this formula in the numericalSimilarity class ? Which methods should I extend ? thanks -- View this message in context: http://lucene.472066.n3.nabble.com/How-to-define-custom-numerical-similarity-scores-in-Lucene-tp2637297p2637297.html Sent from the Lucene - General mailing list archive at Nabble.com.
