Hello,  
I'm experiencing limitations with Lens visualization.  
I created a table with long string fields. After 258 char the field disappears:

With 257 char my field is displayed correctly:

Do you know if there is a settings to change this limit?

Thank you.

I guess you are using the default mapping for your keywork you use in aggregated table  
You can change your mapping an increase the ignore\_above and try again  
This may help i guess

```auto
{
  "foo": {
    "type" "text",
    "fields": {
      "keyword": {
        "type": "keyword",
        "ignore_above": 256
      }
    }
  }
}

```

Hello Yassine,  
You are right. Fields longer than 256 char are not processed as keyword to save performance.  
I adjusted the mapping and the visualization works.

Thanks for your help.
