Can you delete a field from a document in Solr index?

Question

I have a big index, and during the indexation process there was an error. So to avoid reindexing which takes several days, I want to simply delete specific field and reindex. Is there any suggestion?

Answer 1

You cannot. The solution would be to get the document, store temporarily in the memory, delete it, update the required field (remove, add) and then add the document back to the index.
