Hello, I am using ES Java api to run queries against ES. I have a field in ES which has int data. When I run regex filter on that field im getting number format exception. Can't we use regex with numbers? is it only for string fields? Thanks -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Yes. copy the int field value to a string field with copy\_to or manually. Am Donnerstag, 8. Januar 2015 09:56:40 UTC+1 schrieb AK: > Hello, > I am using ES Java api to run queries against ES.
