匹配部分数字的全文搜索

Question

日安。

我用couchDB存储"firstName“、"lastName”、“道布”和"idNumber“等实体的数据。(还存在其他各种动态数据，但现在不重要。)

我已经创建了一个全文搜索索引，以索引特定类型的文档，并设置为仅搜索上述字段。搜索非常适合"firstName“和"lastName”，也有部分匹配。

但是，对于idNumber，必须给出确切的数字。对idNumber的部分搜索不起作用。例如，如果'7605054321089‘是idNumber，而我搜索'760505432'，则不会返回任何内容。如果完全输入idNumber，则返回成功。我已经摆弄了FTS区下的房产，但没有用。

我的出生日期字段根本不起作用。我不能搜索那个领域，但我已经停放了，直到我让idNumber工作至少。

描述过滤器的JSon如下(对大小表示抱歉)：

对于couchbase FTS中的idNumber搜索，可能是因为您试图进行精确匹配搜索吗？你可能想试试前缀搜索..。

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