elasticsearch - 俄罗斯词霸的搜索结果错误

Question

这些分析器设置的索引为products。使用查询стекло进行搜索可返回空结果，但使用查询стеклоы可以很好地进行搜索。

PUT /products
{
  "settings": {
    "analysis": {
      "filter": {
        "russian_stop": {
          "type": "stop",
          "stopwords": "_russian_" 
        },
        "russian_stemmer": {
          "type": "stemmer",
          "language": "russian"
        },
        "russian_synonym": {
          "type": "synonym",
          "synonyms": [
            "айфон => iphone",
            "хонор => honor"
          ]
        }
      },
      "analyzer": {
        "ru_en": {
          "tokenizer": "standard",
          "filter": [
            "lowercase",
            "russian_stop",
            "russian_stemmer",
            "russian_synonym"
          ]
        }
      }
    }
  }
}

GET /products/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "multi_match": {

将这些映射添加到索引设置

"mappings": {
    "properties": {
      "name": {
        "type": "text",
        "analyzer": "ru_en"
      }
    }
  }
