Yes, but deleting fields from the schema only means that _future_ documents will throw an "undefined field" error. All the documents currently in the index will retain that field.
Why you're hitting an OOM is a mystery though. But delete field isn't removing the contents if indexed documents. Showing us the full stack when you hit an OOM would be helpful.
