I have multiple types of documents in one index. Most of the documents are type 1. When the first document from type 2 added to the index, the visualization failed to return the document and I got "Request Timeout after 30000ms". The visualization has a filter to include type 2 documents only and sort on a new field in type 2 which does not exist in type 1 documents. Does anyone know how to solve the timeout issue? ---

Hello Felix, Where do you see this timeout error? Can you please post a screenshot of it? Also what do your Kibana and elasticsearch logs say? Thanks, Bhavya ---
