Multiple mapping types sharing some field names with different datatypes

[Yarden Bar]

Hi all,
A question about collection (or mapping, I'm an ES user).

I have a use-case where I index AWS CloudTrail logs. currently, in ES, I
use the CT eventName as document type for dynamic mapping.
There are several event types which use the same field name but with
different datatype.
Example: eventName1, my_field_name, int
                eventName2, my_field_name, string

In ES, when a mapping has multiple types, fields with same name must have
the same type. is that also the case with Solr? is it related to Lucene?

Thank you in advance,
Jorden
