elasticsearch完全匹配，包含哈希值

Question

I am facing problem with elastic search, i am using query to search data from document. following is the query to search single data from document.

"query": {
      "filtered": {
     "query": {
         "query_string": {
            "query": "'.$lotnumber.'",
            "fields": ["LotNumber"]
                           }
                      }
            }
     }
   }'

It is working fine for simple value but if $lotnumber contains any value with hash in between then it is showing all the data from document.any one here who can help me to resolve problem of searching exact value from document with hash value ??

Answer 1

The first things that I would think of in this case is make the field lotnumber not-analyzed in your mapping. That should do the trick.

In your mapping

"album": {
  "type": "string",
  "fields": {
    "raw": {
      "type": "string",
      "index": "not_analyzed"
    }
  }
}
