Casting Values

Edit page

Cast allows explicit conversion from one data type to another as long as types are compatible.

SEARCH /bank/


{
  "_query": {
    "balance" : {
      "_integer": 2221.82
    }
  }
}

In the above example cast 2221.46 to integer, which later is internally converted to 2221.0 (as the “balance” field is a float).

The following example will convert the integer 84535 to text "84535":

SEARCH /bank/


{
  "_query": {
    "contact.postcode" : {
      "_text": 84535
    }
  }
}
