Search saved visualization and dashboard using sub string when I have the name with underscore

[ghost]

Hi,
If i have saved my search or visualization or dashboard name like "sample dashboard". I can search it using its substring "dashboard". But if i have the name "sample_dashboard" like that, when i search it using "dashboard" substring, It is not listing. Is it possible to add it in future list to match the substring with entire saved name without boundary restriction.
