问题
I changed the simple analyzer on a field to Standard analyzer and tested it locally and it's working fine. I don't have to re-index all my documents in ES.
But according to this SO post and this ES doc, looks like we need to re-index if we add/change the analyzer on a field.
I am confused as its working fine now and it would take consider amount of time if I do the re-indexing and want to avoid it, if it's not required.
Let me know if somebody faced the similar situation and what they did ?
Edit :- I am using the ES 1.7 version and I changed the analyzer on a field and just started the app again, I think my app just update the latest mapping to ES.

If you change an analyzer, of course you need to reindex your data, or at the very least the field whose analyzer was changed.
