Couchbase 全文搜索匹配部分数字

Question

美好的一天。

我正在使用 couchDB 存储一些实体的数据，其中包括 "firstName"、"lastName"、"dob" 和 "idNumber"。（其他各种动态数据也存在，但现在不重要。）

我创建了一个全文搜索索引来索引特定类型的文档，并设置为仅搜索上述字段。搜索对于 "firstName" 和 "lastName" 也非常有效，也有部分匹配。

但是，对于 idNumber，必须给出准确的号码。对 idNumber 的部分搜索不起作用。例如，如果“7605054321089”是 idNumber，我搜索“760505432”，则不会返回任何内容。如果我完整输入idNumber，则成功返回。我把FTS部分下的属性都弄乱了，没用。

我的出生日期字段根本不起作用。我无法在该字段上搜索，但我已将其停放，直到我至少让 idNumber 起作用。

JSon 对过滤器的描述如下（抱歉大小）：

非常感谢任何帮助，谢谢。

对于 couchbase FTS 中的 idNumber 搜索，可能是因为您正在尝试进行完全匹配搜索？您可能想尝试前缀搜索...

    {
        "from": 0,
        "size": 10,
        "query": {
            "field": "name",
            "prefix": "bobble"
        }
    }
