Couchbase全文搜索搭配部分号码

我正在使用couchDB来存储包含“firstName”，“lastName”，“dob”和“idNumber”的某个实体的数据。（其他各种动态数据也存在，但现在并不重要）。

我创建了全文搜索索引来索引特定类型的文档，并设置为只在上述字段中进行搜索。该搜索对于“firstName”和“lastName”也完全适用于部分匹配。

但是，对于idNumber，必须给出确切的数字。部分搜索idNumber不起作用。例如，如果'89'是idNumber，并且我搜索'760505432'，则不返回任何内容。如果我完全输入idNumber，它会成功返回。我已经弄清楚了FTS部分的属性，但没有用。

我的出生日期字段根本不起作用。我无法在该字段上搜索，但我已经停止了该操作，直到我至少获得idNumber才能工作。

JSON的描述如下过滤器（遗憾的大小）：

任何帮助，将不胜感激，谢谢。

为couchbase FTS IDNumber搜索，这可能是因为你正在尝试一个完全匹配搜索？你可能会想尝试一个前缀搜索...

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

你被点上。我改为ConjunctionQuery，其中每个合并都是带有标记化搜索术语的PrefixQuery。现在，诸如“Pet Smi”之类的搜索会返回“Peter Smith”。很好，谢谢。 –
