Is there a way to search by Hebrew root? For example, if I search the WTM database for אמן (aleph, mem, nun), it won't pick up אמנתו (emunato; aleph, mem, nun, tav, waw) in 1 Samuel 26:23. In order to catch emunato in 1 Samuel 26:23 I have to search for אמונה (emuna; aleph, mem, waw, nun, heh). I'd like to be able to cast a wider net and catch everything based on a root like אמן. Is that possible?

thanks,
Charles
