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?

(I have also posted this in Kibana forum but got no response.)

Hi Xavier,

Thanks for your reply! ES and Kibana are both version is 5.5.1.

Let's say I have 2 type of documents, type1 and type2.

type1 has fields: type, field1, field2, field3, ...  
type2 has fields: type, field1, sequence

I have a lot of type1 documents in ES. When I added the first type2, I ran a query with sorting on sequence.keyword. Kibana timed out and I got "Request Timeout after 30000ms".

Hi,

Ok, can you look at the log file of elasticsearch if there is some errors ? May be the query is not good and Kibana doesn't figured out.
