Hello,

 ![image](https://us1.discourse-cdn.com/elastic/original/3X/9/5/95503e4f8be7708eb11f5dc0cb189ad19e2b01a1.png)

Length of string is 5 , but why is it returning 3 by counting only unique characters ?

Same with words in a string

Hi @Pranusha119,

try `doc['special_char.keyword'].value.length()`

Let me know if that's what you expect to get.

Hi @Marta_Bondyra

It's retuning 1 instead of 5

Oh ok, sorry, I didn't understand your question before – unfortunately, to my knowledge you cannot do it – once you index your field as keyword, it will only count unique values. Maybe you could add a string field at indexing time that would store all the characters as a string and then you could print out the string length?

I don't have any other ideas, maybe someone else has.
