Hello !

I use logstash to save my CSV files in ElasticSearch.  
I need to delete my old datas before each treatment.

Example :

- a new CSV file is copied in my directory
- logstash delete items in elasticsearch with a query =\> { "query": { "match": { "DATA":"test" } } }
- logstash insert datas from CSV to elasticsearch

I can not use this [solution](https://discuss.elastic.co/t/replace-the-indexed-data-with-new-data/25442) because I need to delete ALL my datas with a query.

Can someone help me?

Thanks (sorry for my bad english ^^)

I don't think there is an clean way to do this with ES+LS, you may need to script something to delete data from ES and then call LS on the files.
