How to match the value of an array using this key in an elasticsearch array of a pair of key values?

I have an array of pairs key value. Is it possible to establish an exact match value keyand then check its value value?

Example: The following doc oracle_propspresents an array with pairs of names, values. I need to check if it has a key "oracle_cursors", and then check to see if it exceeds 1000.

GET /eg/message/_percolate
{
   "doc": {
      "client": {
         "name": "Athena",
         "version": 1,
         "db": {
            "@type": "Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 64bit",
            "oracle_props": [
               {
                  "@name": "open_cursors",
                  "@value": 4000
               },
               {
                  "@name": "USER_ROLE_PRIVS_COUNT",
                  "@value": 1
               },
               {
                  "@name": "CREATE_PERMISSION",
                  "@value": "Y"
               }
            ]
         }
      }
   }
}

Below is my percolator.

I also need to check the following so that it returns 3as my result

  • "client.name" should be "Athena"
  • "client.db. @type" should be "Oracle" and then go ahead and check below the point
  • "client.db.oracle_props. @name" not found.
  • , "oracle_cursors", , < 1000
