Document ID conventions

Elastic Stack Elasticsearch

Hello,

I have not used ES before and am having trouble finding any guidelines
on what constitutes a valid document ID (that follows the type in
index and get operations).
The examples in the guide use numbers while the auto generated IDs are
base 64 UUIDs based on a 128 bit number.
Are the document IDS restricted to the string representation of
numbers or are they arbitrary strings?
If strings, what characters are allowed (eg I expect a '/' is not
allowed as it is the delimiter for URIs, any other) ?
Any other restrictions on what cannot be used for document IDS, such
as reserved IDs?

Regards
Mauri

There are not constraints on characters that can be used as the id. Even '/'
can be used, though you might need to escape it, for example, id of value
"1/2" will be passes like this:

curl -XPUT localhost:9200/test/type1/1%2F2 -d '{
"field" : "value"
}'
