Well, I cannot still completely relate to the solutions by you guys, am looking into it as how could I achieve that with my application. Thanks ! One thing, that I want to know is how to avoid full re-indexing, that is, what I need is I don’t want that Solr index all the data every time some docs are added, instead I want it to update it, that is index only newly added docs. I hope this is possible, but how ? Because, currently I am using SolrJ and it re-index complete data each time.

Using this you can delete any number of documents from your index or all your documents depending on the query you specify as the parameter. How you use it is down to your application. You haven't said if your application performs a full re-index, but if so you might find it useful to index a version number for your data which you increment each time you perform the full indexing. Then you can increment version, re-index data, delete data for old version number. -----Original Message----- From: Khare, Kushal (MIND) [mailto:kushal.kh...@mind-infotech.com] Sent: 04 November 2019 15:03 To: solr-user@lucene.apache.org Subject: [EXTERNAL] RE: Delete documents from the Solr index using SolrJ Thanks! Actually am working on a Java web application using SolrJ for Solr search. The users would actually be uploading/editing/deleting the docs. What have done is defined a location/directory where the docs would be stored and passed that location for indexing. So, I am quite confused how to carry on with the solution that you proposed.
