Hi Please give us more context. You can start with telling us which crawler you are using and more about your architecture. It is NOT Solr's responsibility to add/delete documents on its own. it is the client (crawler) that has to know when a document is stale or gone from the source, and then the crawler needs to explicitly send a delete request for that doc.
