Question

我使用的是ES 5.5，我的要求是在匹配字段时允许最多两次编辑。

在ES中，我的值为 124456788 ，查询的格式为 123456789

"fuzzy": {
                            "idkey": {
                                "value": **"123456789"**,
                                "fuzziness": "20"

                            }
                        }

据我所知，这两个数字之间的编辑距离是2。但它甚至与模糊属性不匹配为20。

我做了一个解释api电话，这就是我所看到的

我期望匹配的值是124456788但是ES查询在内部没有将其转换为模糊查询中可能的匹配参数之一。

我是否需要使用不同的ES方法来完成这项工作？

Answer 1

这是一个简单的索引和搜索。

PUT /myIndex/type1/1
{
    "key":"123456789",
    "name":"test"
}

GET /myIndex/_search
{
    "query": {
        "fuzzy": {
            "key": {
                "value": "124456799",
                "fuzziness": 2
            }
        }
    }
}

它总是与给定的键匹配。 fuzziness值2或更高可以。

Elasticsearch - 使用模糊编辑距离是不准确的
