bq: can this be used as an unique value instead of generating the
hashcode for the urlField
Don't do this. The _version_ field is used internally for optimistic
locking etc. I'd be _very_
cautious about co-opting this for anything else.

Thanks , I also noticed that the mandatory _version_ field is also
uniquely generated for every document in the collection , can this be
used as an unique value instead of generating the hashcode for the
urlField.
I want to avoid creation of a custom unique filed if _version_ field
which is mandat
OK. So it sounds like doctorURL is a good key, but you don’t like the special
characters. I’ve used MD5 hashes of URLs before as a way to convert unique
URLs into unique alphanumeric strings in a repeatable way. I think most
programming languages contain libraries for doing that as you feed t
Sorry,its actually doctorUrl, so I dont want to use doctorUrl as a lookup
mechanism because urls can have special characters that can caise issue
with Solr lookup.
I guess I should rephrase my question to ,how to auto generate the unique
keys in the id field when using SolrCloud?

You mention you already have a unique Key identified for the data you’re
storing in Solr:
> doctorId
If that’s the field you’re using to uniquely identify each thing you’re storing
in the solr index, why do you want to have an id field that is populated with
some random value? You’ll be using
Just tried adding id while keeping id type=
"string" only blank ids are being generated ,looks like the id is being
auto generated only if the the id is set to type uuid , but in case of
SolrCloud this id will be unique per replica.
Is there a way to generate a unique id both in case of SolrCl
Thanks.
So the issue here is I already have a doctorId
defined in my schema.xml.
If along with that I also want the field to be automatically
generated for each document do I have to declare it as a as

Looking a little deeper, I did find this about UUIDField

“uuid” isn’t an out of the box field type that I’m familiar with.
Generally, I’d stick with the out of the box advice of the schema.xml file,

Hi All,
I am seeing interesting behavior on the replicas , I have a single
shard and 6 replicas and on SolrCloud 4.10.1 . I only have a small
number of documents ~375 that are replicated across the six replicas .
The interesting thing is that the same document has a different id in
each one of
10 matches
