How to change column title from Elasticsearch to Kibana

I thank you very much for trying to help, but what I need is to save a Search and then use this Search on a Dashboard, I will not use Visualization.

Also, I noticed that only one of my fields are being searched, how odd, is it something on my java class object?
I have a field/column log, that I need it be searchable, can you help me on this too? Or should I open another post here?
