带有标准分析器和编号的Elasticsearch完成建议

Question

尝试使用标准分析器在完成字段上索引数字时出现错误。

映射：

PUT music
{
    "mappings": {
        "_doc" : {
            "properties" : {
                "suggest" : {
                    "type" : "completion",
                    "analyzer": "standard"
                }
            }
        }
    }
}

索引：

PUT music/_doc/1?refresh
{
  "suggest" : [ 1234, 5678 ]
}

这是我得到的错误：

[parsing_exception] failed to parse [null]: expected text or object, but got VALUE_NUMBER

我必须输入字符串吗？

Answer 1

您只需要将数字放在双引号（即字符串）中

PUT music/_doc/1?refresh
{
  "suggest" : [ "1234", "5678" ]
                ^    ^  ^    ^
                |    |  |    |
                 here and here
}
