Hi,
I'm creating a type name that contains a dot in its name. ES is warning me
not to do this:
"... Type [type.name] contains a '.', it is recommended not to include it
within a type name"
Why is it recommended not to use dots? I'd like to know what kind of issues
this may cause.
Thanks,
Philippe

When using the syntax of my\_type.my\_field in different places (like term query as the field name, then the type will not be properly recognized).
