NumberFormatException when using regex filter with int field

[AK]

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

Elastic + Kibana Server Specs Recommendation

[AK]

Hi,

I recently launched ELK and I'm receiving about 3,000,000 - 8,000,000 docs 
per day (~ 5GB)
I'm running on AWS on a small server, and after a week of data collection 
the system becomes very very slow, mainly when I am looking for data older 
than 2 days.
Do you have a recommendation for servers in points such as cpu, memory and 
iops and elstic settings like shards.

Thanks
AK

Kibana Search Question

[AK]

Hi,
i'm using ELK for stop my API logs
My message contains a json with an API request, something like that

{"initObj": {"mediaType": 0, "pageSize": 100, "pageIndex": 0, "exact": 
false, "orderBy": "NONE", "orderDir": "ASC", "orderMeta": ""}

I'm looking to find all the massages where "pageSize" in greater than 50.
Is there a way to do so? Without filtering pageSize in logstash

Thanks
AK
