[Solrj] How can I get unique field name?
Hi all,
I am writing a custom query response writer and I would like to handle the
unique key field without knowing his actual name to stay generic.
My question is: how can I get the uniqueKey fieldname of a result document?
Regards.

There is no absolute requirement that a Solr schema have a unique key field,
so you could get a null value for the field.

Thank you Mikhail,
Yes it does.
I can access it throu the SolrQueryRequest object.
this.uniqueKeyFieldName = req.getSchema().getUniqueKeyField().getName();

Hello Zakharia,
org.apache.solr.schema.IndexSchema.getUniqueKeyField()
Does it help?
