I have a form which provides suggestion drop down.  
The form has stopped showing suggestions and when I checked log the error below is logged whenever the form is used.

Can you please tell me what is this error stating and how can I fix this?

Elasticsearch.Net.ElasticsearchServerException:

all shards failed; shardFailures {

When I try to debug this in Visual Studio, I receive this error:

**The remote server returned an error: (400) Bad Request.**

Note that this is an Ajax request on keyup event.

anyone ?

Using the Visual Studio debugger, would it be possible for you to capture the complete request body being sent to Elasticsearch and paste it here?

I couldn't find the request body in VS Debug, so I got it using Fiddler
