Hello, Well, you could remove the write permission for all segment files. Or, make a custom UpdateProcessor that intercepts *:* operations and stops a delete in its tracks. This is what we did, protect the search against me. Keep in mind that a negative query can also delete everything, so you can check if the numRows of the proposed delete query is equals to the number of documents.
