Hi, you could do something like kNN: http://en.wikipedia.org/wiki/K-nearest_neighbors_algorithm Simply perform an MLT query and count the categories of the top-N docs. Additionally, you could weight the categories by score. http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-mlt-query.html I don't think there is anything directly usable via the API to classify documents. Maybe there is some neat trick using aggregations in ES 1.0. Hannes -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
