i have around 15 indexes in my elastic . There is a column which contains some predefined number of values(texts), But i want to change some of the values .  
e.g if there is a value "A" =\> i want to change it to "B"

I want to do it over existing elastic data.

Is there any way to modify existing data in elastic with condition?

ES doesn't have columns, only fields and their values.

Have a look at [https://www.elastic.co/guide/en/elasticsearch/reference/5.2/docs-reindex.html](https://www.elastic.co/guide/en/elasticsearch/reference/5.2/docs-reindex.html)

yea i wrote columns in mistake...  
But my problem is to update existing data in the same index, i don't want to re index.  
I just want to update some of the existing field values.

An update is a reindex under the hood anyway.
