Note: the following crude mockup is designed only to illustrate the preferred logical structure of the search, not to suggest how it should be implemented; even at the former task, it is flawed, since the 'in senses' radio-button option apparently allows one to search for features 'within senses' that do not in fact exist within senses (e.g., etymologies, forms). It is debatable how useful this would be even if correctly expressed (i.e., search for the coexistence within a sense of features A and B, limited to senses that fall within entries that also contain feature 'C').
searching for "liverous" automatically searches also for leuerous, lywerous, leuereus(e, lyvereus(e, etc.
searching for "tortous skin" automatically searches for all phrases whose elements appear as co-variants with tortous and skin in the MED.
tortous skin turtu skinne tortu sckin tortus scinne tortuse scin tortuce schin tortouse shine tortois x chin tortes skene tortuge skijn turtuse kyn tortuces kin cortucis skins skinse chinne etc.
search "tortoise skin" (selecting tortoise sb. and skin sb.), which = MED "tortouse skin" + variants.
