Have a look at the ES docs on their site. There are several ways, from sending a JSON command to deleting the data directory depending on how clean you want ES to be.
In general my opinion is that PIO is an integration framework for several services and for the majority of applications you will not need to deal directly with the services except for setup. This may be an exception. In all cases you may find it best to seek guidance from the support communities or docs of those services. If you are sending a REST JSON command directive it would be as shown here: https://www.elastic.co/guide/en/elasticsearch/reference/1.7/indices-delete-index.html <https://www.elastic.co/guide/en/elasticsearch/reference/1.7/indices-delete-index.html> $ curl -XDELETE 'http://localhost:9200/<index_name>/' The Index name is named in the UR engine.json or in pio-env depending on which index you want to delete.

The input is separate and can be deleted without affecting the model. Each Engine handles model’s it’s own way but most use the model storage in pio-env. So deleting those will get rid of the model. The UR keeps the model in ES under the “indexName” and “typeName” in engine.json. So you need to delete the index if you want to stop queries from working. The UR maintain’s one live copy of the model and removes old ones after a new one is made live so there will only ever be one model (unless you have changed your indexName often) On Dec 21, 2017, at 4:58 AM, Noelia Osés Fernández <no...@vicomtech.org <mailto:no...@vicomtech.org>> wrote: Hi all! I have executed a pio app data-delete MyApp. The command has outputted the following: [INFO] [HBLEvents] Removing table pio_event:events_4...

Why is this happening? I expected to get either an error message or an empty result like {"itemScores":[]}. Any help is much appreciated.
