Hi Tanya,
Even I had the same question , (Can we add our own JSON format query and use it in Kibana?). Actually what we want is we want to run the following command which is in JSON format in Kibana search bar .
{"index":"class_detail","query":{"query_string":{"query":"*","analyze_wildcard":true}},"filter":[]}
Now question would be why we need to run the above JSON query , we are aware that in search bar we can only run normal key value format search , something like "Name":"vikas". Now I want to apply deep search , so for that I have to design a JSON query which provide us more detailed data . So is it possible to use such query ?
