如果我在索引设置中使用keyword_repeat过滤器，那么当使用should通过bool查询搜索文档时，只搜索匹配条件的第一个字段。Elasticsearch版本：8.7.1
创建索引

curl -X PUT "elasticsearch:9200/my-test-index?pretty" -H 'Content-Type: application/json' -d'
{
  "settings": {
    "analysis": {
      "analyzer": {
        "default": {          
          "tokenizer": "default_tokenizer",
          "filter": [
            "lowercase",
            "keyword_repeat",
            "default_stemmer"
          ]
        }
      },
      "tokenizer": {
        "default_tokenizer": {
          "type": "standard"
        }
      },
      "filter": {
        "default_stemmer": {
          "type": "stemmer",
          "language": "english"
        },
        "unique_stem": {
          "type": "unique",
          "only_on_same_position": true
        }
      }
    }
  },
  "mappings": {
    "properties": {
      "field1": {
        "type": "text"
      },
      "field2": {
        "type": "text"
      }
    }
  }
}
'

添加文档

curl -X POST "elasticsearch:9200/my-test-index/_doc/1?pretty" -H 'Content-Type: application/json' -d'
{

"field1": "running man",
"field2": "other text"

}
'

搜索文档

curl -X GET "elasticsearch:9200/my-test-index/_search?pretty" -H 'Content-Type: application/json' -d'
{
  "query": {
    "bool": {
      "should": [
        { "match": { "field2":  "running" }},
        { "match": { "field1": "running" }}
      ]
    }
  }
}
'

回复：

{
  "took" : 243,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 0,
      "relation" : "eq"
    },
    "max_score" : null,
    "hits" : [ ]
  }
}

我希望文件能被找到。
但是具有不同字段顺序的请求（field 1，field 2）

curl -X GET "elasticsearch:9200/my-test-index/_search?pretty" -H 'Content-Type: application/json' -d'
{
  "query": {
    "bool": {
      "should": [
        { "match": { "field1":  "running" }},
        { "match": { "field2": "running" }}
      ]
    }
  }
}
'

查找文档

{
  "took" : 62,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 1,
      "relation" : "eq"
    },
    "max_score" : 0.92058265,
    "hits" : [
      {
        "_index" : "my-test-index",
        "_id" : "1",
        "_score" : 0.92058265,
        "_source" : {
          "field1" : "running man",
          "field2" : "other text"
        }
      }
    ]
  }
}

我希望should条件的工作方式与OR条件类似，因此无论查询中字段的顺序如何，两个查询都应该返回结果。如果我从索引设置中删除keyword_repeat，一切都按预期工作，两个查询都能找到文档。
使用keyword_repeat过滤器的索引标记列表

curl -X GET "elasticsearch:9200/my-test-index/_termvectors/1?pretty&fields=field1,field2"

{
  "_index" : "my-test-index",
  "_id" : "1",
  "_version" : 1,
  "found" : true,
  "took" : 116,
  "term_vectors" : {
    "field2" : {
      "field_statistics" : {
        "sum_doc_freq" : 2,
        "doc_count" : 1,
        "sum_ttf" : 4
      },
      "terms" : {
        "other" : {
          "term_freq" : 2,
          "tokens" : [
            {
              "position" : 0,
              "start_offset" : 0,
              "end_offset" : 5
            },
            {
              "position" : 0,
              "start_offset" : 0,
              "end_offset" : 5
            }
          ]
        },
        "text" : {
          "term_freq" : 2,
          "tokens" : [
            {
              "position" : 1,
              "start_offset" : 6,
              "end_offset" : 10
            },
            {
              "position" : 1,
              "start_offset" : 6,
              "end_offset" : 10
            }
          ]
        }
      }
    },
    "field1" : {
      "field_statistics" : {
        "sum_doc_freq" : 3,
        "doc_count" : 1,
        "sum_ttf" : 4
      },
      "terms" : {
        "man" : {
          "term_freq" : 2,
          "tokens" : [
            {
              "position" : 1,
              "start_offset" : 8,
              "end_offset" : 11
            },
            {
              "position" : 1,
              "start_offset" : 8,
              "end_offset" : 11
            }
          ]
        },
        "run" : {
          "term_freq" : 1,
          "tokens" : [
            {
              "position" : 0,
              "start_offset" : 0,
              "end_offset" : 7
            }
          ]
        },
        "running" : {
          "term_freq" : 1,
          "tokens" : [
            {
              "position" : 0,
              "start_offset" : 0,
              "end_offset" : 7
            }
          ]
        }
      }
    }
  }
}

我试着测试了不同版本的elasticsearch，得到了以下结果：
8.8.1 -按预期工作8.8.0 -按预期工作

8.7.1 -存在问题****8.7.0 -存在问题

8.6.2 -按预期工作。
