如果我将某个字段的similarity function设置为类似于BM25,那么More Like This是否会使用该相似性得分为其选择顶部字词进行分离布尔搜索(或者是默认使用tf-idf,如文档所示:[MLT] selects the top K terms with highest tf-idf to form a disjunctive query of these terms.)?另外,返回的订单/分数是否反映了默认的tf-idf相似性或我设置的相似性?
[MLT] selects the top K terms with highest tf-idf to form a disjunctive query of these terms.
