Special characters in Elasticsearch field names are:
. (for navigation between name components)
(for delimiting name components in _uid, should work, but is discouraged)
- (for matching names)
There are also some restrictions on type names for mappings:
- must not start with underscore "_"
- must not contain comma ","
- must not contain hash mark "#"
- usage of point "." is discouraged but possible

Hi,
Besides from special characters, elasticsearch also does not seem to allow
other characters in fild names, such as <,> and a comma. Could anyone
please provide me with a full list of illegal characters for field names.Many thanks,
Eli
