Is it possible to specify an Index when I use the elasticsearch logstash filter? I can't possibly let it search through everything. My google searches did not bring me any further, since googling for something with the words 'logstash, elasticsearch, filter' often leads to wrong results.. ---

Are you talking about the elasticsearch _input_? Yes, it has an [`index` parameter](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-elasticsearch.html#plugins-inputs-elasticsearch-index). ---

no ES filter does not yet has that option but you can patch and add that option easily ---

> [@niksfirefly](#): > > but you can patch and add that option easily hi niksfirefly, i'm in this trouble too, the logstash-filter-elasticsearch index param couldn't input like %{+YYYYMMDD}, since all my indices are in this format and i don't want to search for everything, how could i patch it? ---
