Is there a way to set analysis for a field?

I want to search for the value of productSN.
Using the default analysis configuration, it seems that the result cannot be found.

{
"userType":2,
"productSN":"1452007220003",
"leadName":"叶孙达",
"leadPhone":"15858805027",
"leadProvinceId":"a60cb377-993f-e711-80cb-005056bae90b",
"leadCityId":"7b1199ec-9c3f-e711-80c9-005056bab658",
"leadCountyId":"9e4d412e-a03f-e711-80c9-005056bab658",
"leadAddress":"朗诗德测试",
"installPhotoImages":[

]

}

Fields also have this format

"body": {
  "original": "{\"List\":[{\"NickName\":\"改变自己13998076912\",\"OpenId\":\"ocYHs4tDe2-fQvyUsVCUV9DLGok4\",\"UnionId\":\"oUNcX1nUekRgyTAG2DPjt2F0h_nQ\",\"Platform\":\"MpMall\",\"Sex\":2,\"Country\":\"中国\",\"Province\":\"辽宁\",\"City\":\"鞍山\",\"HeadImgUrl\":\"https://wx.qlogo.cn/mmopen/vi_32/OGdVxseFfkGX16BRkY1zsqywGpOt1L90UwlYKXTNhQXcNpJF94RTOPou1WNUMd8lic1e1YhQ0iaWqIrnuPt4shzA/132\",\"ContentType\":null,\"Extension\":\"\",\"ObjectKey\":\"/photo/0/2f8ab46814cb4c8497c4c911a7b5339f\",\"Domain\":\"img-cdn.lonsid.co\",\"Bucket\":\"lonsid\"}]}"
}

I'll search the OpenId value.

I feel like I need to customize an analysis and I need some suggestions.

I used the pipeline JSON processor to solve the problem
