使用两个文件时同义词规则无效

Question

我有两个几千行的同义词文件，这里是导致问题的示例：

en_synonyms 文件:

cereal, semolina, wheat

fr_synonyms 文件：

ble, cereale, wheat

这是我得到的错误：

{
  "error": {
    "root_cause": [
      {
        "type": "illegal_argument_exception",
        "reason": "failed to build synonyms"
      }
    ],
    "type": "illegal_argument_exception",
    "reason": "failed to build synonyms",
    "caused_by": {
      "type": "parse_exception",
      "reason": "Invalid synonym rule at line 1",
      "caused_by": {
        "type": "illegal_argument_exception",
        "reason": "term: wheat analyzed to a token (cereal) with position increment != 1 (got: 0)"
      }
    }
  },
  "status": 400
}

我使用的映射：

PUT wheat_syn
{
  "mappings": {
    "wheat": {
      "properties": {
        "description": {
          "type": "text",
          "fields": {
            "synonyms": {
              "type": "text",
              "analyzer": "syn_text"
            },
            "keyword": {
             "type": "keyword",
              "ignore_above": 256
            }
          }
        }
      }
    }
  },
  "settings": {
    "number_of_shards": 1,
    "analysis": {
      "filter": {
        "en_synonyms": {
          "type": "synonym",
          "tokenizer": "keyword",
          "synonyms_path" : "analysis/en_synonyms.txt"
        },
        "fr_synonyms": {
          "type": "synonym",
          "tokenizer": "keyword",
          "synonyms_path" : "analysis/fr_synonyms.txt"
        }
      },
      "analyzer": {
        "syn_text": {
          "tokenizer": "standard",
          "filter": ["lowercase", "en_synonyms", "fr_synonyms" ]
        }
      }
    }
  }
}

两个文件都包含术语 wheat 当我从其中一个文件中删除它时，索引创建成功。

我考虑合并这两个文件，所以结果是：

cereal, semolina, wheat, ble, cereale

但在我的情况下，我无法手动执行此操作，因为这会花费很多时间（我将寻找一种以编程方式执行此操作的方法，具体取决于此问题的答案）

Answer 1

找到一个简单的解决方案：

我没有使用两个文件，而是将 en_synonyms 和 fr_synonyms 的内容连接在一个文件中 all_synonyms:

cereal, semolina, wheat
ble, cereale, wheat

然后用于映射。
