Illegal characters in elasticsearch field names

Elastic Stack Elasticsearch
1

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

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
