Hi, I indexed the document using Logstash, but if I need to do some preprocessing using PERCOLATOR how can I do it, is there any possiblities to use percolator in logstash, if not what can be the possible solution for this problem ( **TO use percolator before indexing the document** ) ? Best Regards, Navneet ---

You can use the [ES input plugin](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-elasticsearch.html) to do "things", but what do you want to do exactly? ---
