Hello, everyone. I'm running a single index on a 1-shard, 1-node index on Windows 2008. The index is named "vrs" and it holds a mapping for one document type called "listing". I've been feeding roughly 100,000 documents into the index over the last few days with a Windows service that I wrote in C#. I'm using the excellent NEST library to interface with my ES instance. I woke up this morning to discover that all of my documents had simply vanished from my index. There was nothing there anymore. My service doesn't have any calls that would delete the index, though it does remove individual documents when they meet certain criteria. The only clue I have as to what happened are these entries in the log file from yesterday... [2012-05-17 15:20:42,203][INFO][org.elasticsearch.cluster.metadata] [Tutinax the Mountain-Mover] [[vrs]] remove\_mapping [listing] [2012-05-17 15:20:42,948][INFO][org.elasticsearch.cluster.metadata] [Tutinax the Mountain-Mover] [vrs] update\_mapping [listing] (dynamic) There are tons of these that started about 15:20 yesterday. I've had the instance up for a week and this is the first log entry besides those at the instance startup. Any clue what I've done wrong here? If the shard gets too big would it simply empty itself out? If all I'm doing is adding and deleting the same document type should this happen? Any advice you have would be much appreciated. I'm happy to provide any other information you might need. Cheers, Jamie ---

Hi, It looks like you sent a command like : curl -XDELETE localhost:9200/vrs/listing/ Instead of : curl -XDELETE localhost:9200/vrs/listing/1 The first command delete the type and generate this log entry: > [2012-05-17 15:20:42,203][INFO][org.elasticsearch.cluster.metadata] > [Tutinax the Mountain-Mover] [[vrs]] remove\_mapping [listing] Check your code but I think that the problem occurs when you try to remove a doc.
