Hello guys,

I'm trying to learn Elasticsearh and I'm getting confused with Array data types.

I have define 2 text type fields and I have put some test data in to the index. To my surprise, the index accept combination of text and numeric.

I'm getting confuse to understand this ([https://www.elastic.co/guide/en/elasticsearch/reference/6.5/array.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.5/array.html))

Am I misunderstand something here ?

Here is my index mapping

```
{
  "david_idx" : {
    "mappings" : {
      "_doc" : {
        "properties" : {
          "fav" : {
            "type" : "text"
          },
          "name" : {
            "type" : "text"
          }
        }
      }
    }
  }
}

```

And it seems like 'fav' can hold more than just text.

I have insert it as single text

```
  {
    "_index" : "david_idx",
    "_type" : "_doc",
    "_id" : "zWNZy2gBOusqcldvSZ8J",
    "_score" : 1.0,
    "_source" : {
      "name" : "first test",
      "fav" : "apple"
    }
  },

```

and Array

```
  {
    "_index" : "david_idx",
    "_type" : "_doc",
    "_id" : "I2Nay2gBOusqcldvlKED",
    "_score" : 1.0,
    "_source" : {
      "name" : "second test",
      "fav" : [
        "apple",
        "orange"
      ]
    }
  },

```

a numeric field

```
  {
    "_index" : "david_idx",
    "_type" : "_doc",
    "_id" : "JXH-2WgBOusqcldvzl8j",
    "_score" : 1.0,
    "_source" : {
      "name" : "fifth test",
      "fav" : 1
    }
  },

```

even array of nummeric

```
  {
    "_index" : "david_idx",
    "_type" : "_doc",
    "_id" : "vXH_2WgBOusqcldvTl8R",
    "_score" : 1.0,
    "_source" : {
      "name" : "sixth test - number test",
      "fav" : [
        99,
        98,
        97
      ]
    }
  },

```

and mixture of text andm numeric.

```
  {
    "_index" : "david_idx",
    "_type" : "_doc",
    "_id" : "LHEL2mgBOusqcldvEmu1",
    "_score" : 1.0,
    "_source" : {
      "name" : "seventh test",
      "fav" : [
        5,
        "banana"
      ]
    }
  }
```
