用 match query 查询字符串"the lord",结果返回

score=8.081023 "The Second Sun" score=5.412263 "Lord of War" score=4.5157876 "The Lord of the Rings: The Two Towers" score=4.120181 "The Lord of the Rings: The Fellowship of the Ring" score=4.120181 "The Lord of the Rings: The Return of the King"

模糊参数改一下，结果也是一样的。刚接触 Elasticsearch，这排序是正常的吗， "The Second Sun" 评分怎么那么高

按你这个搜出来的应该是这样吧

"hits" : [
{
"_index" : "test",
"_type" : "1",
"_id" : "6NVkW3kBGtH1h4VDFSRZ",
"_score" : 0.86009264,
"_source" : {
"title" : "The Lord of the Rings: The Two Towers"
}
},
{
"_index" : "test",
"_type" : "1",
"_id" : "6dVkW3kBGtH1h4VDVCSG",
"_score" : 0.8239962,
"_source" : {
"title" : "The Lord of the Rings: The Fellowship of the Ring"
}
},
{
"_index" : "test",
"_type" : "1",
