Solr doesn’t have an “external id”, so people aren’t understanding your question.
Each document in a Solr collection has a unique ID. One field is chosen to be that ID. I usually make a field named “id”, but that isn’t necessary. If documents have an ID in the repository, you can send that ID to Solr when indexing the document. Send it in the field you have chosen for the unique ID. When a new document is sent with the same ID, that will replace the existing document with that ID. Also, you say you are storing documents in Solr. I do not recommend using Solr as a primary repository. Use a database for that. wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog) > On Oct 22, 2018, at 2:19 PM, Rathor, Piyush (US - Philadelphia) > <prat...@deloitte.com> wrote: > > Thanks Shawn. > > So we cannot update records based on external id? > > Thanks & Regards > Piyush Rathor > > Please consider the environment before printing. > > -----Original Message----- > From: Shawn Heisey <apa...@elyograg.org> > Sent: Monday, October 22, 2018 2:56 PM > To: solr-user@lucene.apache.org > Subject: [EXT] Re: SOLR External Id field > > On 10/22/2018 12:46 PM, Rathor, Piyush (US - Philadelphia) wrote: >> We are storing data in solr.
