Dashboard: How to filter for multiple search strings ? (ORing or REGEX)

[sigma415]

Dashboard provides a search field, where I can input one search string. e.g. "Radar" and then it shows only all device with "Radar" in their names.
But I want also to add an adiitional search string with e.g. "Motion".

Is it possible to use "OR" keyword or something similar ?
Or use a REGEX expression for filtering ? (e.g. .*Radar.*|.*Motion.*)
