Mishandling of large numbers

[tomasz-sternumiot]

Documents with big numeric values are presented incorrectly (rendered number is incorrect).

Please see very similar issue here: jqlang/jq#1959

Steps to reproduce:

1. Create an index with a field of the unsigned_long type

PUT /my-test-index-000001
{
  "mappings": {
    "properties": {
      "big_number": { "type": "unsigned_long" }
    }
  }
}

2. Index some data

POST /my-test-index-000001/_doc
{
    "big_number": 1234
}

POST /my-test-index-000001/_doc
{
    "big_number": 1016950844191088640
}

3. Query for the data

GET /my-test-index-000001/_search
{
    "size": 10
}

Here is a query result:

Incorrect because 1016950844191088640 != 1016950844191088600

4. You can try to search for a particular values to see how it is really indexed
   4.1 Searching for rendered value → no results

GET /my-test-index-000001/_search
{
    "query": {
        "term": {
            "big_number": 1016950844191088600
        }
    },
    "size": 10
}

4.1 Searching for indexed value → document found

GET /my-test-index-000001/_search
{
    "query": {
        "term": {
            "big_number": 1016950844191088640
        }
    },
    "size": 10
}
